Description

ADJUSTABLE ANTENNA POLE SUPPORT PLATFORM ARRANGEMENT

FIELD OF THE DISCLOSURE [0001] The field of the disclosure is roof mounted antenna mast support arrangements.

BACKGROUND [0002] Antennas are typically located on the roof of a building because that is the location at which there is the most likelihood of receiving the electromagnetic signal that the antenna is built specifically to collect. The collected signal is then directed along an electromagnetic pathway (typically a co-axial cable) to a signal receiver located somewhere within the building. The antenna is not as selective as to only receive a particular frequency but rather a band of frequencies and other frequencies each side of the band to a lesser degree. It is the role of the combination of the antenna, the electromagnetic pathway to a receiver, and the tuning circuit within the receiver, to isolate a particular frequency or very narrow bands of frequencies. Once isolated from all the other frequencies being received by the antenna, the tuned frequency is suitable for demodulation of the additional signals carried by the received frequency. The demodulated signal might for example be a particular television channel carrying both video, audio and control signals, with the demodulated video and audio being respectively presented to the occupant of the building by a video display and an audio speaker.

[0003] An example of an antenna suitable for tuning a suitable band of electromagnetic signal is a Yagi-Uda antenna. Figure 14 depicts an example of an Ultra High Frequency (UHF) band Yagi-antenna 140, suitable for efficiently tuning a UHF carrier signal used to communicate Digital Transmission of multiple Television channels. The antenna depicted is constructed of multiple conductive elements in a very specific physical array of those elements, there generally being a dipole driven element, at least one passive reflector element (slightly longer than the driven element) and at least two but typically six to eight passive director elements (slightly shorter than the driven element). The size, orientation and spacing of all the elements of the array are determined by the frequency band the antenna is intended to collect. So the wave length of the mid-band frequency of the particular band to be collected by the array of conductive elements determines the spacing’s between the elements (e.g. 1/10 to % of that wavelength) as well as the length of the elements of the array.

[0004] The collected signal being some 2% to 3% of the intended collected bandwidth about

2019101253 15 Oct 2019 the centre frequency is tapped off at a junction point of the dipole element, at which the maximum amplitude of the received frequency band is present. The collection of the available frequency band is inherently imperfect, but the combination of the elements, material selection, the remainder of the tuning elements as discussed above and the quality of the tuning circuit in the receiver, all maximise the usefulness of the captured signal.

[0005] One important feature of the depicted Yagi-Uda antenna is that it is designed to receive the maximum amount of electromagnetic energy from one particular direction. The preferred direction that the Yagi-Uda antenna should point is along the arrow 142 shown in Figure 14, noting that the narrow end of the Yagi-antenna is pointed towards the source of the signal to be collected and the reflector element is located at the nominal rear of the antenna. This directionality is referred to as an omnidirectional receive pattern. That directionality is advantageous to the operation of the antenna since the selectivity for signals impinging of the antenna from that preferred direction also acts to reject signals from most other directions and this reduces the influence of otherwise interfering signals. If the Yagi-Uda antenna is pointed other that in the correct direction, the collected electromagnetic energy reduces dramatically. Hence the antenna installer needs to, not only align the antenna at installation (using a handheld signal detection device on the output of the antenna) they must also fix the antenna so as to maintain that alignment at all times into the future.

[0006] The higher above the landscape the receiving antenna - the stronger the signal received from the source of the signal. The radio frequency transmitters and associated transmission towers and antenna are generally located on or near the top of geographically prominent locations such as hills or mountains. The towers on top of those prominent locations support the source transmitting antenna so that the greatest geographic area can be transmitted to. Regardless of the height of the source antenna, the higher the receiving antenna is relative to local ground level, the more likely the signal received will be direct (direct line-of-sight being ideal) from the transmitter, not blocked by electromagnetic signal attenuating and reflecting obstacles such as other hills, buildings and foliage. However, even if there are obstacles it is still better for the antenna to be located as high off the local ground as possible, since that increases the exposure of the antenna to minimally reflected and attenuated signals.

[0007] Placing an antenna on a roof of a building is not an easy task. Each roof is different in many ways, including but not limited to: the roof covering (tiles, slate, timber, iron, etc.);

2019101253 15 Oct 2019 the pitch can vary from a small slope to 35 degrees to the horizontal (particularly when snow is expected); there may be no guttering, but if there is, the guttering may be deep and extend well away from the end of the roof material, the guttering may be narrow, the gutters may be covered with leaf excluder mesh; the roof may also support other articles, such as for example, solar cells, or large surface area thermal heat collector tubes filled with water, and not uncommonly other antennas.

[0008] To further complicate the antenna mounting installation process, the roof material may be poorly maintained or of poor quality. The material of the roof may also not be best suited to supporting an antenna installer during installation. It needs to be recognised that the installer may be on the roof, near its apex or near the roof edge for an extended period. The time spent on the roof by the installer includes the processes of: preparing the roof for the antenna support arrangement to be fitted; installing the antenna support arrangement to the roof structure regardless of the pitch of the roof; preparation of the roof surface material for the mount base; fixing multiple parts of the antenna support arrangement to build a frame to support the pole to which the antenna can be fixed; ensuring the antenna support pole is vertical; fixing other parts of the antenna support arrangement to fix the verticality of the support pole onto which the antenna is eventually fitted; fitting the antenna to the antenna support pole; carefully aligning the directionality of the receiving antenna by swivelling the antenna about the support pole to maximise the reception of the wanted electromagnetic signal from the distant source transmitter and which may involve adjustments to the antenna support arrangement as well as to the antenna on the antenna support pole; and then once both the antenna support pole is stable and the antenna is properly aligned; fixing all the adjustable fixings so they remain secure for the life of the antenna.

[0009] Of course, all the above mentioned actions by the installer may need to be performed in less than ideal weather conditions adding to the complexity, safety and quality of the work done to install the antenna.

[0010] In addition to the problems in the process of installation there are a number of antenna support arrangements which are partly assembled. However, their partial assembly creates a volume that is not ideal for packaging, transportation, display in retail and wholesale sales environments or for physically carrying those parts onto the roof prior to installation.

[0011] The problem to be addressed is how to minimise the number of and complexity of adjustments required to install the antenna support arrangement and eventually the antenna on

2019101253 15 Oct 2019 to the antenna support arrangement in a challenging environment, while also providing for an antenna support arrangement which has a minimal packaged volume.

Nothing contained herein is to be construed as an admission of the prior art. Applicant expressly reserves the right to demonstrate, where appropriate, that the articles and methods referenced herein do not constitute prior art under the applicable statutory provisions.

DETAILED DESCRIPTION OF EMBODIMENTS [0038] As used in the specification and claims, the singular form a, an and the and include plural references unless the context dictates otherwise.

[0039] The present disclosure may use the term comprise (open-ended) or consist essentially of’ the components of the present disclosure as well as other methods or elements described herein. As used herein, comprising means the elements recited, or their equivalent in structure or function, plus any other element or elements which are not recited. The terms having and including are also to be construed as open-ended unless the context suggests otherwise. As used herein, consisting essentially of’ means that the claimed arrangement, method and system may include elements in addition to those recited in the claim, but only if the additional elements do not materially alter the novel characteristics as claimed.

[0040] Where used herein, the term and/or when used in a list of two or more items means that any one of the listed characteristics can be present, or any combination of two or more of the listed characteristics can be present. For example, if a step is described as containing characteristics A, B, and/or C, the step can contain A feature alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.

[0041] Figure 1 depicts a perspective view of an embodiment of a pole 12 support arrangement 10 suitable for mounting an antenna (not shown in Figure 1 but depicted in Figure 14) thereon. The support arrangement is usable for supporting a pole 12 having a first end 14 and a free end 16 (not shown in Figure 1 but illustrated in Figure 14). Not shown is an antenna 140 (as illustrated in Figure 14), the antenna is adapted by including an antenna fixing bracket 142 which allows the height of the antenna to be freely moved to, and then a slight tightening of the pole fixing member allows the antenna to adjustably rotate about the pole. The rotation is required so as to align the antenna so it is pointed towards the radio signal transmitter (Television Broadcast Antenna and Transmitters) and once the maximum possible signal is detected, the pole fixing member is fully tightened to attach the antenna 140 to the pole 12 intermediate the first end and the free end of the antenna support pole (sometimes referred to as a mast).

[0042] The support arrangement has the following elements which are described in the

2019101253 15 Oct 2019 context of embodiments, since there may be alternative arrangements, features and elements of the characterising features. Figures 1 and 2 depict a brace arrangement 18 and in the depicted arrangement, the brace arrangement has a first end 20 and at least two second ends 22a and 22b. In the depicted embodiment, the brace arrangement is a single rod shaped, also as depicted in Figures 3, 4 and 5, formed by creating a bend at the middle of the single rod, which becomes the first end 20 of the brace arrangement. The spacing between the free ends 22a and 22b is arranged to be the same as the spacing between two apertures 24a and 24b in the base 24 (Figures 1 and 2), into which the free ends are, in use, going to articulate during the installation process and to engage with, once the support arrangement for the respective pole is set to be fixed into the required orientation.

[0043] The two second free ends 22a and 22b of the brace arrangement are further shaped.

In this embodiment the free ends are formed into z-bend dog leg shape as depicted in greater detail in figures 3 and 4 and in use in Figures 6 and 6A.

[0044] The embodiment disclosed includes just one rod shaped to suit the described need, but it is possible for the brace arrangement to consist of other arrangements, such as in one example, two separate braces (stays) joined by a fixing (welding, clip, brace, flattened ends which are bolt and nut joined, etc.) to form a first end 20, and for that fixing to also be adapted to fix to the pole fixing member 30 (Figures 1 and 2), which could include use of the bolt and nut to affix to the pole fixing member using an aperture in the pole fixing member, alternatively by providing a further aperture in one or both rods and use of a further bolt and nut to secure the first end 20 to the pole fixing member 30 The described alternative fixing and brace arrangements are not shown in the figures, but are mechanical equivalents. There could be more than two braces and thus more than two free ends. Those free ends and would then have respective points of articulation and engagement with the base 24 (Figure 1) and the base may have a different shape to that disclosed in the embodiments. For example, the base may have three apertures located on three extended portions of the base, and many other configurations are possible while providing two or more articulation and engagement means for respective ends of a brace arrangement.

[0045] In the embodiment disclosed in the Figures 1 to 5, both second free ends 22a and 22b are adapted for articulation with respect to the base 24 (Figure 1), wherein the Z-bend dog leg shape provides both: articulation during the set-up of the support arrangement; and engagement with the base once the brace arrangement is in order for fixing.

2019101253 15 Oct 2019 [0046] Articulation is provided by the ends being able to move within the apertures 24a and 24b in the base so that small rotation (typically in the substantially vertical plane) is possible during the time that the pole is being manipulated by the installer. The apertures are straight through holes in the base, sized to allow the ends to enter and exit the aperture so that the outermost bend of the Z-bend protrudes from the aperture below the base as is depicted in Figure 6. The inside of the dog-leg bend rests on the inside wall of the aperture and partially on the top surface of the base, and positioned in that way, prevents the free end from moving further through the aperture in either direction, and becomes set in that position once the pole fixing member 30 is tightened and thus fixed onto the pole 12, creating a three point (tripod) fixing arrangement between the base 24 (for two of the points of contact) and on the pole fixing member 30 for the third point.

[0047] The articulation is simple and unrestricted, thus making the task of final adjustment of the verticality of the pole much easier than trying to actually bend the prior art braces. Prior art braces did not move with respect to the base since they were welded to the base. Thus, when the pole is being manipulated and tested for verticality, the installer needed to have and apply their strength to bend the brace material to suit the angle required, all the while keeping the pole in the vertical position. Since the welded bracing rods were strong in the first place the installer would need to sometimes bend them multiple times, to ease them into the most suitable shape.

[0048] The installation process of prior art mounting arrangements was no simple arrangement, since the prior art braces are designed to be strong enough to support the pole (mast) and supported antenna during high winds and other environmental effects (such as supporting bird and wildlife perching or sitting on the antenna). The processes described in relation to the prior art arrangement are time consuming and require that the installer to have good purchase on the roof and for the situation to be safe for the described actions to be exercised. The alternative provided by the arrangement of the embodiment described avoids all the exertions described and allows the installer to mainly concentrate on the verticality of the post (mast).

[0049] The articulation is also useful for when the support arrangement is to be packed for transport, packed for sale or taken on to the roof by the installer. Both free ends 22a and 2b can articulate such that the brace arrangement can lie against the base 24 and have a packaged state, as depicted in Figure 6A, such that the brace arrangement is still captured in their ίο

2019101253 15 Oct 2019 respective apertures in the base. This configuration also improves the installation process since the base and the brace arrangement can be easily carried in situ onto the roof, thus reducing the need to construct the mounting arrangement on the roof.

[0050] The base 24 includes a pivotable engagement element 28 (Figures 1 and 2) adapted to pivotally engage with and support the first end 14 of the pole 12. In this embodiment the pivot is provided by a bolt located in an aperture (not shown) in the first end of the pole (mast) and enters the aperture after passing through an aperture (not shown) in one side 28a of the engagement bracket and when the bolt exits the pole, it then enters an aperture (not shown) in another side 28b of the engagement bracket. The axis of rotation of the pole is such that, in use, the pole can be rotated into a substantially vertical orientation, regardless of the angle the base 24 has to the ground, since the base is mounted on a slopping roof structure and the angle of the roof is not known before installation, since the location of the proposed installation may change once installation commences. For example, because of the lack of line of sight from the planned location to the transmitter, or the intrusion of trees and the obstacles since the original planning was done, or the condition of the roof at the planned location of installation is discovered not to be suitable. In any event the same support arrangement is thus suitable for most roof structures and roof slopes.

[0051] The base 24 is adapted, in the embodiments disclosed, for engagement with the second ends of the brace arrangement, of the embodiment disclosed, by in this arrangement, the provision of two apertures in the edge region of the base opposite the location of the pivotable engagement element 28 and the apertures are spaced to match the spacing of the ends of the brace arrangement. The apertures are located, in the depicted embodiment, on an upturned portion 24c of the base. The angle of the upturned portion relative to the plane of the rest of the base is about 20 degrees but can vary and the angle assists to present a surface onto which although not necessary can assist to support a portion of the inside of the dog-leg bend as it rests on the inside wall of the aperture and partially on the top surface of the base portion 24c.

[0052] The pole fixing member 30 is adapted for movement and adjustment along the pole intermediate the first end 14 and the free end of the pole so that the pole 12 can be easily adjusted for verticality. In this embodiment the first end 20 of the brace arrangement 18 is fixed to the pole fixing member 30, while second ends 22a and 22b of the brace arrangement 18 articulate with respect to the base 24 and engage with the base. The pole 12 is adjustable

2019101253 15 Oct 2019 into a vertical orientation and fixed in that orientation by the fixing member 30.

[0053] In an embodiment, the pole fixing member 30 is a substantially U-shaped clamp having a nut and bolt, or butterfly nut, so that the tightening of the clamp is simplified for the installer although that is not the only means for such simplification. Thus, not only is the final tightening made easier, but also the initial slight tightening of the pole fixing member, so that the pole 12 can be retained in roughly the correct orientation, but still allow the pole fixing member to slide up and down the pole while the pole is manipulated into the vertical orientation.

[0054] Once the antenna 140 (Figure 14) is placed onto the pole 12, the antenna can be adjusted rotationally and then fixed to the vertically orientated pole.

[0055] Figures 12 to 14 disclose a further embodiment of the base using the same embodiment of the support arrangement as disclosed in other figures. This embodiment of the base includes a variation to the planar version disclosed in Figures 1 to 11, which are preferred for installation on flat rooves. Whereas the embodiment of Figures 12 to 14 includes a stepped profile, most suited to installation on tiled rooves. Figure 14 most aptly discloses the placement of the stepped version of the base onto the tiles.

[0056] The installation of this embodiment will be described in detail but the principles are equally applicable with suitable and practical variation to the planar version of the base. The centre line of the batten supporting the tile over which the base is to be mounted is marked and using the base as a template the position of the two holes to be drilled through the tile into the batten is marked. Caution needs to be taken to avoid cracking or breaking of the tile during the drilling process. It is preferable for a clearance hole to be drilled for each of the mounting screws used to fix the base to the roof and it may be prudent to drill a pilot hole into the batten for each fixing screw.

[0057] Cleaning below the drilled tile and the top of the tile will ensure there is a clean surface for the application of silicon sealant to the high spots of the tile and to the area about the holes and into the holes themselves. The pad of sealant on the tile and the apertures through the tile will perform a number of functions, including padding to isolate the base from the tile during any buffeting of the pole and affixed antenna to the support pole, and protect against the ingress of water, dust and wind to the roof space below the tiles. Once the base is positioned, typically before the pole and antenna are attached, suitable screws are inserted into

2019101253 15 Oct 2019 the prepared holes and firmly screwed into the batten, thus attaching the base to the roof structure. If winds are expected within certain standardised measurements for the area then additional bracing maybe required.

[0058] During all the steps performed by the installer safety is paramount and the embodiment of the innovation disclosed herein enhances the safety of the installer by making the installation easier and less reliant on actions which could otherwise affect their safety.

[0059] Although there has been a disclosure of preferred forms, the specific embodiments thereof as disclosed and illustrated herein are not to be considered m a limiting sense, because numerous variations are possible. Applicants regard the subject matter of this disclosure to include all novel and nonobvious combinations and sub-combinations of the various elements, features, functions, and properties disclosed herein. No single feature, function, element or property of the disclosed embodiments is essential. The following claims define certain combinations and sub-combinations of features, functions, elements, and properties that are regarded as novel and nonobvious. Other combinations and sub-combinations may be claimed through amendment of the present claims or presentation of new claims in this or a related application. Such claims, whether they are broader, narrower, equal, or different m scope to the original claims, also are regarded as included within the subject matter of applicants' disclosure.
