I don't disagree with you. I've used it with great results, as have many people over the years. I'm not starting an argument (this is more for my own personal education), but I just don't see much of a benefit... at least that would drive me to rip it out of my plane. Yes, it's true that lower loss is better, but what range increase will you really see? I did some calcs to highlight the differences between the two cable types. Granted, they are simple and there are many other variables that I won't pretend to know about, but here it is: Parameters - 15 ft Coax Length 1:1 SWR (assumed) 8W Carrier Output Power Results - RG-58 - 6.8W Output Power (.69dB total loss) RG-8X - 7.0W Output Power (.58dB total loss) Perhaps it's more of a question about how far you can receive? Glenn, if so, can you show me? I just don't know. Matt
