Antenna verticale multibanda
Single conductor to be connected for all decametric bands excluding 80 meters
Field Day Vertical Antenna
The 1/4 wave vertical element is mounted above the bottom mast separated
Wide Band 40, 75, & 80 Meter Antenna
The 80m/40m antenna the thicker a dipole wire is relative to its length, the wider the bandwidth
Vertikalantenne fur 40 und 80m
Vertical multiband antenna for 40 and 80m. However, a groundplane requires a good radial network, otherwise it will not work well. I laid some fence mats and 10m long wires around the base

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
