While this is more commonly a problem with aeronautical mobile stations, it also happens around here for stations on hills between several repeaters or whose beams line up with more than one repeater.

Hi Dan and you make a valid point about feedline loss. I am feeding M2 HO
LOOP with 65 ft of 9914F low loss coax which incidentally enough is a "direct bury" coax. I use a 35 ft run of 9914F for my Ringo Ranger II. I have a 50 ft run of the same 9914F direct buried feeding my Hustler 5-BTV vertical. At HF frequencies especially with 9914F there is virtually no loss at 50ft. Link for 9914F coax, jumpers and assemblies and coax loss tables. The 9914F is within .1 db of 9913 loss figures but is more flexible and can be buried directly into mother earth.... 1. http://www.radio-ware.com TY for making a good observation but in my case your "preaching to the choir".
