Antenne G5RV
It is a multiband antenna which is similar to a center-fed or a Levy antenna of particular dimensions chosen to obtain a low impedance on frequencies close to 3.5 7 and 14 MHz
Coaxial fed multiband windom antenna
This simple multiband antenna works on all HF bands from 3.5 to 30 MHz, including WARC bands other than 10.1 MHz
Build a sturba curain antenna for hf bands
The Sterba Curtain, as designed is non resonant.There are a couple of bands where the swr will drop to 3:1
Inverted V for 17-20-30-40m
A 4-band 17-20-30-40m antenna that rolls up into an small Grundig antenna case

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
