Thanks for the reply. I'm running a cheap cobra 19 mobile unit on a 3 amp power supply. The feed point of my antenna is about 30ft off the ground but I'm still not quite over the tree line. Transmission line is 50 ft of RG58. No amplifier. I've got good ears with the current setup and can get on page on the DX if conditions are favorable. The matching coil on my antenna is a random number of turns. So i might have just gotten lucky there but my swr sits about 1.3:1 in the middle of the bandwidth.
