First of all let me thank everyone that answered my questions about LMR-400 cable and the desense issues I have been having. So far tests right up to the antenna with a dummy load have shown no desense so to me that leaves the antenna. After some discussion with a Diamond representative who didn't have a lot of technical background this is what I have learned. The model DP-GH62 appears to cover the 6 meter band in two segments. 50 to 51.5 and 52 to 54 Mhz. There is a 9.5 pf cap across a coil at the base and with the cap in place it is supposed to operate from 50.to 51.5 and removing the cap moves it up to 52 to 54. My repeater frequencies are 52.810 out and 51.110 in. So I need to either move my input frequency up or so If I play with the value of the cap say 12 to 25 pf and make the antenna resonate somewhere from 51 to 53 Mhz?
