Antenna Vertical Links →
10 mt wire jpole
Radiator 14 or 18 gauge strander copper 16.5 feet
20 mt wire Jpole vertival end feed
Same as dipole advantage is omindirectional pattern and low angle radiation when hauled up high
20-Meter J Pole Vertical
The J pole vertical is built from a fifty-foot TV push up mast
40/15M band sloper
The tower guy wires could be used as additional antenna radiators. The antenna that most suited this application was a 40m band sloper as the guy wire to be used was slightly longer than a 1/4 wave length at 7 MHz
