That wouldn't quite reach the ground from my antenna but LMR600 has good specs. How are the connectors to work with? Do you need a flex jumper at the antenna to allow the rotor to work? I am using 230 feet of RG-213 which has about 3.5 loss according to the specs. It works, but I don't do Moon Bounce with it. Willis 'Cookie' Cooke K5EWJ
