Antenna Overview
The new "keeper" 80M antenna is a pair of raised 1/4-wave (68') verticals in the pine woods on our sloping lower property.
Two verticals, each is 68' of 16-gauge aluminum fence wire
(Princess Auto farm section, $30 for 1,300' roll)
Three elevated 66'-long radials for each vertical
Relay control box switches for NE, SW or broadside signal
Uses one SPDT relay to switch for end-fire patterns, and if you want a second SPDT to short the phasing line for broadside bidirectional at 1 dB gain over a single vertical.
Exhibits up to 5 S-units of front-to-back between endfire direction
