I am replacing my Cobra 29LTD radio and replacing my cheap oil coil antenna with a Wilson Trucker 18 inch shaft and a Galaxy DX959 modded out. What I am not sure of does Coax length make a big difference in mobile performance? I have right now in my Tacoma I believe is 18 feet of coax which is way to much causing me to coil it up under the truck. I bought 9 feet of coax that I think will be just long enough..am I doing the right thing here?
