Description
Satellite Antenna Assembly The invention to which this application relates is an antenna assembly of the type which is provided to receive and/or transmit digita' data signals which are broadcast via a satellite broadcast system and one, or more, satellites.
Typically, in order for satellite service broadcast data signals to be received at a number of premises, each of the premises will be provided with receiving apparatus. The apparatus typically includes an antenna or dish assembly which includes the dish attached to a bracket which, in turn can be located on a support such as a pole or wall, and typically externally of the premises.
The assembly also includes an arm protruding to the front of the dish and is located most typically below the bottom edge of the or can be provided to pass through an aperture in the lower part of the dish antenna, preferably in the manner described in the applicant's co-pending application. The arm is typically located at the rear of the dish to the mounting bracket and towards the opposing end of the arm there is provided a mounting for one or more Low Noise Blocks (LNB's). The LNB is provided to receive the data signals which are transmitted on known frequencies and which are received by the dish and reflected from the same to the lN B. The LNB typically includes or is connected to a feed horn which allows the data signals of the required type to pass through the same and the feed horn leads to a waveguide which allows the passage of selected received data signals along selected paths to processing apparatus. The data is then passed, typically via cable and/or wireless connection to data processing apparatus located internally of the premises and at which the received data is processed, typically into video and/or audio, to allow selected television and/or radio services and/or auxiliary services to be provided to the subscriber internally of the premises.
This invention is primarily directed towards the antenna assembly mounted externafly of the premises but the advantages obtained by the present invention have a beneficia' effect on the use and performance of the system as a whole and on the service which is provided to the subscriber.
The antenna dish is required to be located at the time of installation with respect to it's geographical location and the location of the one or more satellites from which data is to be received from and/or transmitted to. In order to achieve this the mounting bracket is provided with adjustment means which allow the adjustment of the elevation and/ or azimuth positions of the dish with respect to the remainder of the bracket. Once the correct position is achieved, the adjustment means can be locked off with the aim being to maintain the dish in that position and thereby provide the optimum data signal reception and transmission. Another aspect which is critical to the optimum reception and transmission of the data signals is correct shaping of the antenna dish and in particular the front or reflecting face of the same. Any indents in the face can be a problem as can variation in the shape of the dish face over time due to flexing of the same and which can use the dish to be come misaligned wit the data processing components mounted on the arm of the antenna assembly and hence increase errors in the received data signals and the video and/or audio which is generated therefrom. These problems can cause a significant increase in the errors in the received or transmitted data and hence the video and/or audio data service which is provided.
The problem is also found to increase in dishes of larger size and which, may therefore be less rigid and therefore more prone to deformation.
It is found that in practice the conventional Htetface and join between the dish and the mounting bracket include points of contact of the bracket with the dish and each of which are typically formed by a bolt which passes from the antcnna into receiving aperturcs in the bracket. WhHc these points of contact ensure good mechanical location of the dish with the support bracket thcy can themsdves form strcss points from which deformation of the dish can occur.
The aim of the present invention is to provide a satellite antenna assembly of a type for fitment to a support means such as a pole or wall and which can be provided with accurate location and performance characteristics at the time of installation and thereafter SO ensuring that the quality of reception of data signals by the assembly is sufficient to aiiow the services generated from the received data to be provided and maintaincd in subsequent use.
In a first aspect of thc invention thcre is providcd a data signal antenna assembly, said assembly including an antenna dish having a receiving face and mechanically located with a support bracket via a plurality of engagement means at spaced locations and wherein said support bracket includes a support portion which includes a support face which is shaped to substantially match the shape of that portion of the rear face of the antenna dish with which the support portion is positioned when the said antcnna dish is mechanically located with the support braclcct.
In one embodiment the support portion is formed of a sheet material.
In one embodiment the support portion includes location means for the engagement means used to mechanically locate the support bracket with the antenna dish.
Preferab'y, when the antenna dish and support bracket are mechanically ocated, at kast part, typically the majority, and preferably substantially all of the support face is in contact with the rear face of the antenna dish.
In one embodiment the parts of the support portion which provide location of the engagement means are raised or dimpled with respect to the remainder of the support portion so as to be positioned in a phne in advance of the plane of the remainder of the support face with respect to the contact with the rear of the antenna dish. This dimpling allows tolerance for the support portion to take into account the effect of the tightening of the engagement means rather than the effect of the tightening having any effect on the shape of the front face of the antenna dish.
Typically the engagement means comprise a bolt which is passed through an aperture in the antenna dish from the front face to the rear face and the shaft of the bolt passes through an aperture or slot in the support portion and engages therewith or more typically engages with a nut located on the shaft to the rear of the support portion slot or aperture. Tightening of the same causes the support portion to be brought into contact with the rear face of the antenna dish In one embodiment the support portion is partially formed by a substantially frustoconical part which at the wider end is provided with the support face and at the opposing end is connected to a second part of the support bracket.
Typically the relative positions of the support portion and the second part of the support bracket are selectively adjustable so as to allow the azimuth and/or elevation of the antenna dish to be adjusted with respect to the support surface to which the antenna assembly is located. In one embodiment a plate is provided which engages with the rear of the antenna dish and the second portion of the support bracket, typically said plate is located within the support portion of the support bracket.
in one embodiment the support portion also receives and is engaged with an arm which extends from the support portion to the front of the front face of the antenna dish. Typically the arm includes a mounting bracket at the opposing end to mount one or more components such as an LNB and waveguide thereon.
Typically the arm passes from the support portion, through an aperture in the antenna dish and to the front of the dish.
Typically the arm includes a portion intermediate the ends of the arm which has a substantially curved external surface and at, or adjacent to, at least one of the ends of the arm there is provided at least one engagement surface for the location of a component or bracket therewith such that the external surface at or adjacent to the said end is of a different shape to that of the said portion of the arm.
In one embodiment the opposing ends of the arm are provided with at least one substantially flat engagement surface. Most typically at one or each end there are provided at least two, typically opposing, substantially flat engagement surfaces.
In one embodiment the portion of the arm with the curved external surface is formed so that the said external surface is substantially circular or elliptical in cross section and thereby provides the curvature with the arm itself being, in a preferred embodiment, straight.
In one embodiment the curvature of the external surface of the said portion of the arm is selected so as to minimise the reflective effect of that part of the arm with respect to the data signals.
Typically the aperture is formed so as to substantially match the externa' shape of the arm on said intermediate portion.
A specific embodiment of the invention is now described with reference to the accompanying drawings; wherein Figures 1 and 2 illustrate an elevation and side elevation of an antenna assembly in accordance with the invention; and Figures 3-6 illustrate perspective and elevation exploded views of the components of the assembly in accordance with one embodiment of the invention.
Referring firstly to Figures 1-2 there is illustrated an antenna assembly 2 in accordance with one embodiment of the invention. The assembly includes an antenna dish 4 having a front, data reflecting, face 6 and a rear face 8. The faces can be shaped to suit specific purposes in a conventional manner and the dish is typically parabolic in shape. The assembly also includes a support bracket 10 located to the rear of the dish and connected thereto. The support bracket includes means 12 to allow the bracket to be engaged with a support, in this case in the form of a pole (not shown), and which allows the assembly to be mounted at a required location therewith. lhe support bracket also includes adjustment means 14 which can be of a conventional form and which allow the adjustment, typically, of the elevation and azimuth positions of the antenna dish with respect to the support to be made and hence aflow the dish to be provided in the optimum position for reception, and transn-iission, of broadcast data signals.
The antenna assembly 2 a'so includes an arm 16 which extends from an end 20 at the rear of the dish through an aperture 18 in the antenna dish to the opposing end 22 which is located at a spaced distance 24 from the front face 6 of the antenna dish.
At the end 22 of the arm there is provided a mounting bracket (not shown) for the reception of data signal receiving and/or transmitting components thereon (not shown) such as an LNB, feedhorn, waveguide and the like and it will therefore be appreciated that these components have to be securely located in position in order to keep errors in the receipt and transmission of the data signals to a minimum.
The aperture 18 is provided with a peripheral lip portion 28 which is curved inwardly from the front face 6 towards the rear face 8 of the antenna dish such that the diameter of the aperture 18 at the front face is greater than the diameter of the aperture 18 at the rear face 8 of the antenna dish.
The arm includes an intermediate portion 32 which is substantially circular in cross section in this embodiment such the arm is straight along the longitudinal axis and is provided with an external surface which is curved. This serves to reduce any problems which may be caused by the reflections from the arm with respect to the receipt of the data signals on the front face 6 of the antenna dish vhich acts as a reflecting surface for the transmitted data signals. At each end 20, 22 of the arm there are provided engagement surfaces 36,38 and 36',38' respectively on opposing sides of the arm and which are substantially flat as shown and lie in planes which are substantially parallel with the ongitudina axis of the arm.
The provision of the engagement faces ensures that the respective support and mounting brackets engagement faces can be securely and accurately fitted to the respective ends of the arm via the relatively flat engagement faces 36, 38 as opposed to trying to fit the same to curved surfaces and thereby ensures that the operation of the components provided on the brackets and ocation of the same with respect to the assembly and antenna dish can be maintained in the desired manner after in stall at ion.
Referring now in more detail to Figures 3-6, the components of the assembly are shown in a separated form for ease of reference. In particular it is shown that the support bracket 10 is formed of a support portion 40 and a second part 42. The adjustment means 14 are provided to allow adjustment of the antenna dish 4 with respect to the support as indicated by arrow 44 and arrow 46 by allowing selective relative movement between the support portion 40 (and antenna dish connected thereto) and the second part 42 which is retained in a fixed position on the support. This adjustment is typically only performed at the time of installation of the antenna dish to ensure that the same is set at the optimum position for receipt of the data signals.
The support portion 40 includes a substantially frustoconical body portion 46 which includes a lower part 48 which engages with the end 20 of the arm 16 and so it will be appreciated that the arm is held in a fixed position with respect to the antenna dish so that both the antenna dish and arm are moved together when any installation adjustments are undertaken via the support bracket. A plate 52 is provided which is retained within the support portion and attached to the second part 42 of the support bracket via engagement means 54.
The support portion also includes a support face 50 which is provided of a shape which substantially follows the shape of the portion 56 of the rear face 8 of the antenna dish at which the same is positioned when the assembly is formed. The said portion 56 is shown in hatching in Figure 6 for reference.
Typically when the assembly is formed, the support face will be in contact with the rear face 8 of the antenna dish and this acts to spread the stresses and strains which may affect the dish during installation and thereafter away from the six points of engagement 58 of the antenna dish to the support bracket shown in Figure 2.
Ihe points of engagement 58 are each formed by a bolt 60 which passes through an aperture 62 in the antenna dish and is received in a slot 64 in the support face. A nut 66 is then moved onto the threaded shaft of the bolt 60 and tightened to secure the antenna dish to the support bracket 10. The slots 64 are typically provided in a dimpled portion 68 of the support face with the dimple being such that the plane of the dimple lies in front of the plane of the remainder of the support face with respect to the rear face 8 of the antenna dish. This dimpling means that when the engagement means for the antenna dish to the support face are tightened the tightening effect can act to flatten out the dimples to an extent such that the plane of the dimple portions 68 then lies in lie or substantially closer to the plane of the support face and so any stress or strains or movement which occur during this process are absorbed by the support face 50 and not by the antenna dish.
Ihe current invention therefore allows the antenna dish shape, which is critical to the performance of the assembly as a whole in providing relatively error free received data signals, to be maintained in a form in which the same is provided from the factory. This is due to the fact that the potentia' stresses and strains and movement of faces of the dish which may occur in conventional assemblies are avoided by providing the support face of the support portion of the mounting bracket in the manner described above which acts to absorb stress and strains which may occur during forming and installation of the assembly and also during the subsequent use of the apparatus due to the location of the support face on a significant area, and typically continuous area, in the form of portion 56, of the rear face 8 of the antenna dish. Thus the support face of the support portion provides support during forming, installation and subsequent use of the assembly and assists in maintaining the integrity of the antenna dish receiving surface and hence the performance of the apparatus.
