MEANS FOR INCREASING THE CAPACITY OF RADIOAERIALS.

Application filed March 9, 1925.

This invention relates to means for reducing the resistance of the aerials of radio receivers and its object is to thereby increase the power of the signals received. It is well known by those skilled in the art that an increased surface for aerials produces an increased capacity to receive signals and it is common to use tape stranded wires or woven wire tape to give this increased area with decreased resistance.

In the present instance any sort of single wire, stranded wire or tape aerial may be used, and upon this aerial is placed a series of flat metal plates which give added area as well as something of a directional efilect to the signals received.

It is, of course, understood that the aerial is improved both for receiving and broadcasting.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may he modifications thereof.

Figure 1 shows the aerial erected and attached to a radio receiving set. I

*igure 2 is a side elevation of one of the plates used.

Figure 8 is an end view of one of the plates.

Figure 4 is an end view of a mod1fied form of a receiving plate, and,

Figure 5 is a longitudinal sectional. view of the plate shown in Figure 4:.

The numerals 1 and 2 indicate the poles for the support of the aerial 3; said aerial Serial No. 13,996.

having insulators at 4 and 5 and being secured at one end by means of a rope 6 pass ing through a pulley 7 all in a well known manner which of itself forms no part of the present invention.

The aerial 3 may be made of any desired type of material and it has secured along at different lengths a series of triangular plates 8; said plates are provided with ears 9 and 10 at each end, which ears are soldered to the aerial at 11 and merely bent around an insulating tube at 12. Flanges 13 and 14: are placed on the edge of the plate to give it something of a whirling motion, since it has been ascertained that with said flanges the results are better than without them.

It has also been found that a thin cone as illustrated at 15 with a tube 16 at its small end to receive and be secured to the aerial, gives excellent results; the tube 16 being long enough to prevent the cone from touching the aerial at its wide end.

WVhat I claim is as follows, but modifications may be made in carrying out the invention shown in the drawings and in the above particularly; described form thereof, within the purview of the claim herein:

Means for increasing the capacity of radio aerials comprising a triangular shaped thin sheet metal plate, having its edges bent over to form flanges, V shaped ears at each end of said plate to clamp on an aerial wire, one of said ears being clamped directly on said wire and the other being insulated therefrom.

Intestimony whereof I have hereunto set my hand this 27th day of January A. D.
