7 Mhz Vertical antenna
The secret with this antenna is to install as many radials as you can around the base of the antenna, they can be anything from 1/8 wave or longer
A HF multiband vertical
The antennas may be installed at height near one meter above the ground. Resonance counterpoises should be used at this placement
Verticale con circuito risonante alla base dai 160-ai 10mt
