The 5 band pipe vertical That's 20, 17, 15, 12 and 10 meters, KL7JR
A simple, cheap and easy to build 33 feet long vertical antenna that works DX on 20 10 meters including Warc bands
The portable random wire vertical
This simple 40 thru 10 meter wire vertical should enable you to get on all the new HF bands
Utilisation d'un pylone autoportant en antenne verticale
It may be interesting to use a high pylon supporting other antennas as a vertical antenna
Una antena hibrida de 3,5 - 7 Mhz que ocupa poco espacio
The occupied surface is limited to that of the roof of the house, 9 x 12 m, and this leads to a very economical realization of vertical antenna for two bands

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
