2 Claims.
This invention relates to antennae and more particularly to an antenna which is especially in tended for use with television receivers.
An object of the invention is the provision of an antenna which is adapted for use in receiving both high and low band television signals.
A further object of this invention is to provide an antenna having separate elements for high and 10W frequency bands and in which th said elements are adjustable for direction of sig nal.
A still further object of this invention is to provide an antenna having such elements which are adapted'for separate orientation with direc- "tion of signals.
Further objects and advantages of this invention will be more clearly understood from the following description and the accompanying drawings in which:
Fig. 1 is a perspective view of an antenna embodying my invention.
Fig. 2 is an enlarged plan view of said antenna with portions broken away and the connecting bar omitted therefrom.
Fig. 3 is a further enlarged fragmentary view on line 3-3 of Fig. 4.
Fig. t is a side view, in central vertical section. I
As shown in the drawings, my improved antenna comprises a pair of tubular element bars 5-5 which are insulated from each other and supported on an insulating sleeve 6 that is secured to a suitable mast I, preferably'by means of a U-bolt 8.
The said element bars 5-5, have electrically connected thereto, a pair of element vanes, or wings, 9-9 to which are secured a pair of Q-bars I ll-l0, by means of which the said antenna is adjustably connected to conductors lI-ll with a pair of connecting members l2-l2 that are slidably adjustable on said Q-bars for varying the effective length of the Q-bar in tuning the antenna.
The vanes 9-9 are preferably connected by means of an insulated bar l3 which is swivelly secured to each of the vanes for adjustably retaining them at relatively fixed angles.
Each of the Q-bars Ill-l is provided with a connecting bolt M which is electrically connected to the Q-bar and extends through the ends of 50 the associated vane 9 and thereby provides an electrically connected unit, at each side of the antenna, consisting of a vane 9, a. tube and a Q-bar I9; each of said units being insulated 5 from the other by the tube 6.
The bars 5-5 will provide a low frequency band antenna while the vanes 9-9 will provide a high frequency band antenna. Also, in the operation of my antennae, the bars 5-5 will act as reflectors in relation to the vane.
In the use of my improved antenna, the bars 5-5 are first adjusted on the mast for orientation with the direction of the low frequency signals and the vanes 9-9 may then be adjusted for separate orientation with direction of the high frequency signals, by turning them upon the bolts ll-ll, and the connecting bar l3 will maintain the said vanes with a fixed included angle between them; this being important when adjusting the vanes for direction of signal.
The vanes 9-9 are preferably fixed with an included angle of substantially 75 degrees between them and this angle is maintained by the bar l3 when the said vanes are adjusted for different directions. In Fig. 2, the said bar 13 is omitted.
r I claim:
1. An antenna of the character described comprising a mast, a tubular insulating sleeve mounted on said mast, a pair of oppositely extending straight tubular bars mounted over the end portions of said sleeve and spaced from each other, a U-shaped tubular vane pivotally and directily connected to each of said tubular bars; the said vanes being relatively disposed at an angle to each other and to said tubular bars, a pair of Q-bars each electrically connected to one of said vanes and one of said tubular bars by means of a connector projecting from the end of each Q-bar and extending through the legs of its corresponding vane and a tubular bar and the insulating sleeve, and a tie bar of insulating material pivotally connecting the said vanes and permitting adjustment thereof for different directions while maintaining a predetermined fixed included angle between them.
2. An antenna of the character described comprising an insulating sleeve, a straight tubular bar mounted over and projecting from each end of said sleeve, a U-shaped tubular vane pivotally REFERENCES CITED The following references are of record in the file of this -patent& v
