Remote Controlled Antenna Switch
A controller board around a wemos d1 mini, using an esp8266 micro-controller the esp is faster with more ports, way more memory, and better ios
Remote antenna switch
My original Remote Antenna switch was made specifically to select the various driven elements on my Quad
Switch 5 antennas
An antenna switch is a very useful accessory because you can use only one coax-cable for your antennas instead of more
Implementation of Remote polarization switching
The original article suggested using PCB RF Relays, and creating a PCB with 50 ohm

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
