How a yagi antenna works

WebUHF spectrum is between 300 MHz to 700 MHz (assuming that antenna was built prior to 2010) VHF spectrum is much lower and spans the old channel lineup from 2 to 13 with FM Radio in the middle. That goes from about 50 MHz to about 220 MHz. Seeing that the Hydrogen line is about 1.2 GHz, I don't see you having good results with this antenna.

A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; these elements are most often metal rods acting as half-wave dipoles. Yagi–Uda antennas consist of a single driven element connected to a radio transmitter and/or … Ver mais The antenna was invented by Shintaro Uda of Tohoku Imperial University, Japan, in 1926 with a lesser role played by Hidetsugu Yagi.
