I'm looking for the best coax for a Kenwood TM-D710GA radio for a 3/4 NMO fender mount. A coax cable that comes pre-attached like the one below (sans fender mount, got that already via @nakman / Gamiviti). Based on what I've researched, since it will be a short run (the base unit will be hidden in the PS rear cargo panel) it appears that signal loss will be minimal so was thinking either RG-58 or RG-8X should be sufficient. Is that accurate? If so, I haven't been able to find one. Any good sources to purchase from?
