HOW TO MAKE THE GRAY HOVERMAN TV ANTENNA

Описание к видео HOW TO MAKE THE GRAY HOVERMAN TV ANTENNA

This is a easy TV antenna to build picks up VHF and UHF .Tested at 60 miles away from TV towers. Air TV channels transmit on frequencies ranging from 170 MHz to 860 MHz. The VHF-Hi band covers 175 to 230 MHz, while UHF covers 470 to 860 MHz. The gap between is used for cable TV. Receiving all these frequencies is difficult when using a single antenna. The Gray-Hoverman antenna has been designed by Doyt R. Hoverman and it was patented in the sixties. His design only covered a part of UHF band. However, with some improvements, the antenna can receive well both the UHF as well as VHF-Hi. This post will show two variants of this antenna that can be used to receive 170 to 230 MHz channels (5 - 12) and a part of UHF between 470 - 720 MHz (21 - 52 channels) with a minimum gain of 5 - 6 dBi. These are the simplest to build. There are however designs that offer a minimum gain of 8 dBi on VHF and 10 dBi on UHF. These antennas can be used for any kind of signal that can be received on the mentioned frequencies: analog TV, DVB-T, DVB-T2, ISDB-T, ATSC.
