Forgot to mention. The Rotor EZ calibration instructions SUCK! Someone needs to re-write them so they can be understood and applied properly. It takes a while to get it right. I did build mine from t

That will work great. That's what I use. Try to find some decent UHF female connectors for either the LMR-400 or RG213. Or use N type connectors. Seal them up well! Remember to make your last wrap of
