I have completed my experiments with electrical UHF antenna's. I did discover that vertically polarized signals come in at the frindge. I have also found that an additional 3db of signal may be obatined by tuning the antenna for a portion of the UHF television band. With the repack tuning can be employed from channels 25 to 32. This is where most of the channels are now. I got no magic or a proxmity effect that pulled in hundreds of channels. The UHF over the horizon and reflected signals vary greatly with wheather. They come in best on partly couldy days. I am now experimenting with magnetic antenna's. They have no conventional directors and consist of series of loops. The driven, directors and reflectors elecments and directors are loops. I can connect the driven elements in series to drive up the output voltage. We shall see how it goes. Here is paper on the subject. https://orbit.dtu.dk/files/3615193/Appel-Hansen.pdf
