If so how? Well, what you can do with what you have: Check the electrical length with the MFJ (it's in the manual) Connect your transmitter to one end, dummy load to the other, and using the watt meter, check for any noticable loss, looking at the difference between power into the cable, and power out at the other end. You didn't say the length, but with LDF-5, you can look up the specs for loss vs length and see if what you get is about right. > Eventually I want to put a beam on the mast and > a rotor.

Is there a better way? A short length of flexible coax, with stranded copper center conductor. The plated aluminum center conductors won't hold up to the flexing. But... A beam on a repeater? Yahoo!
