Antenna multiband 10,20,40mt
Bi-directional radiation perpendicular to the strands of the doublet Impedance from 50 to 75 ohms depending on the angle of the reverse V
Antenna Half Sloper Multiband 1.8, 3.5, 7, 14, 21, 28 MHz
I made about 25,000 QSOs on it mainly in international contests - in 1.8, 3.5, 7, 14, 21, 28 MHz bands. The antenna also works effectively in WARC bands

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
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
