Did the same here. A small plastic project box with DPDT toggle switches for Pre-Amp On/Off & L & R Polarization for each antenna. E-mail me direct if you want pix.

I did so years ago. Just toggle switches. I had indicator LEDs on the box that I mounted the switches in. As I recall, I used DPDT switches with one pole supplying power to the relay on the antenna, and the other pole to turn on the indicator LEDs. This was for the KLM antennas, rather than the M2, but I assume something similar.

Also like to use LED indicators for visual settings...... Any thoughts ? 73 Jerry KJ4EU
