Tnx to everyone who responded to my polarity switch post......Will take it all in on advisement.....I already had constructed one but did not like its performance. It was very similar to Dino's, but I think his is much better.....May incorporate some of the other ideas as well. TNX AGN......

I picked out wires to power the preamps and polarity switches. I had a row of toggle switches allowing me to turn each preamp on or off, and switch polarity on the antennas. It all worked very well. I miss those AO-10, 13 and 40 days.
I have pictures of the satellite antennas here:

But never took a picture of the switches….

Just wondering if anyone has ever devised a 12 Volt DC Switch console at the operating position to send 12V to the Polarization switches on the CP yagis at the tower?
would toggle switches be okay for that or should I use relays instead? Also like to use LED indicators for visual settings......
Any thoughts ?
