The triple 4-square project antenn
The 40m 4-square will be centered in the 80m one, which will be centered in the 160m 4-square. hence the triple 4-square

80 Meter Antenna
I ran a small single wire from the soffit directly down the side of the building
80 meter doublet antenna design
It is basically an 80-meter dipole fed by a length of 450 ohm ladder line into a balanced antenna tuner
80m Inverted-L Base-loaded for 160m
An antenna for 160 meters inverted " L " for a small garden, with a large loading coil
80 MT Antennas on ARDF
Antenna systems, sensitivity and accurately of 3.5MHz direction finding antennas for ARDF
80m Antenna Spitfire
UA9BA 80m Spitfire Antenna all described antennas have a center element 25 meters high

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
