Just installed a AG-25 (Icom preamp) on my 2M cp yagi. No preamp noise Smeter=0, preamp on Smeter=7. Signals "appear" better after backing down the volume with the preamp. I have 8-10 feet of LMR400uf from antenna to preamp, 50 feet of LMR400 to shack. I suppose I was expecting more "dramatic" results, I realize the AG-25 isn't the greatest and best, but it works well with the 910. Are these real world results for what I have. S7 noise level seems a bit high.
