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
