80 MT Antennas on ARDF
Antenna systems, sensitivity and accurately of 3.5MHz direction finding antennas for ARDF
Antenne doublet epais bande 80mt
It's a classic doublet which is a half wavelength long on 80 meters fed in the center with ladder line
Butternut Notes
The next installation was similar except the antenna was mounted on a 15 foot mast using the STR Kit and 2 65 foot wires as 80 meter radials

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
