Super facil antena VHF 1/4 ONDA
It's about making us an antenita type GP ground plane for the VHF band
Systeme d'antennes verticales en phase
Two vertical antennas lambda / 4 and placed at a distance equal to lambda / 2 are fed simultaneously by the same signal in emission. The signal is applied with a phase shift or 180 degrees
The 5 band pipe vertical
A simple, cheap and easy to build 26 feet long vertical antenna that works DX on 10 20 meters including warc bands
Un commutatore per sloper
I built this switch to switch some sloper for low bands without increasing the number of cossial cable descents
Short loaded vertical antenna portable
Diameter: 62 mm coil height 83 mm / Full height: 121 mm after cutting off a part I didn't need Coil turns: 28

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
