Multiband vertical HF antenna
The antennas may be installed at height near one meter above the ground. Resonance counterpoises should be used at this placement
New Shortened Vertical for 17-20-30-40 Meters
a 4-band, 20' vertical half wave that uses two loading coils with taps. The results appear promising
Shortened 160 meter vertical
Highly effective for 160-meter DX and local work, easy to build and adjust, very economical

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
