80/40 Meter Vertical Antenna
The total height of this antenna is 33 FT,the coils were make from 1/4 aluminum tubing

Antenna Vertical Links →
Full 1/4 wave vertical for 40m
To construct the antenna, I used 6 tubes of each 2m length. Starting at 10mm diameter for the top and ending with 36 mm at the foot
GAP Titan DX Evaluation
The GAP Titan DX It is appx. 25 feet high, and split in the middle with an insulator, allows to operate with acceptable SWR on every band from 80 through 10 meters, including WARC bands
Ground plane direttiva su sei direzioni
Questa e' una antenna adatta per HF se si dispone di un terreno od un cortile in cui piantare tre aste verticali di 1/4 di lunghezza

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
