Is there a way I can replace the factory antenna base and wires with just a aftermarket antenna base and coax? In like most want find and stubs!? A hate the short slanted antenna at the rear. I have a tri magnet NMO base with 4’ whip I want to put close to center of the roof. I have a CB and FM radio configuration splitter to use one antenna for both CB and Fm. But the problem is the nitro antenna system is not regular antenna coax?
