Hello everyone this will be my first post on forum and looking forward to your answers. I’m in the process of setting up my mobile and had a few questions about wavelength. Most of these calculators online give you a coax length of either quarter or half and I’m not sure what value to use. My antenna is going to be a quarter wave whip with hustler spring and fatboy mount. I’m have a custom stainless rod threaded and cut 2 inches to make a full 108 inch antenna. Not sure if that’s necessary but I would rather do it right the first time. I’m running a galaxy 44hp and Carl built 6 pill. I have grounded everything and upgraded wire from alternator to battery. Before I started cutting coax for jumpers and to antenna I was hoping to get some input from you guys. So is it quarter or half wave? Thanks Moose
