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.
