"Once the signal leaves the transmitter's antenna...your on your own" There is no "Holy Grail" combination of antennas and feed lines and there is no "Best", lot's of "Better". Every situation is different. Electromagnetic wave theory and wave propagation are a science unto themselves. We are dealing with the basic laws of physics which we have no control over. After many years of dealing with antennas and feed lines, I used to DX television and I still DX commercial FM, I've learned to follow 4 basic rules when it comes to antennas and feed lines. 1) Do your research. Figure out what best suits your situation; location, inside or outside, what do you listen to etc. 2) Spend as much as you can for your antenna and feed line as this is the weakest link, it's not unusual to spend more for the antenna and feed line than for the radio. I like to use the 55-45 or 60-40 rule with the highest % going to the feed line. An average antenna with a high quality feed line will work better than a "super" antenna with a crappy feed line. 3) Mount your antenna as high as you possibly can without it being a problem or a hassle, stay away form those power lines! Inside or outside, higher is always better. 4) Remember, some days reception will be great some days it will be crap, Mother Nature doesn't give anyone special consideration. Once the antenna is up don't fall into the trap, "If I do this maybe it will be better", "If I change this maybe....". "Increases in performance diminish greatly with the more money you spend" Sit back and ENJOY!
