You could run it within the tubing, but you'll have to really make sure to seal the tubing around the cable, or drill drain holes (of they aren't there already). If water gets in, and can't get out, the tubing will split when it freezes and the water expands. Its a cleaner install, and ultimately its up to you. Personally, I run the wire externally, mainly for ease of access. I can understand how on a T-top, it'll be really noticeable. Just remember to not install the Centerpin connector until AFTER you run the wire. Ask me how many times I've made that mistake.cayman":37t5e7td said:Just got my new 21 SE with a factory T top. Is it O.K. to run the VHF cable through the T top tubing? After spending lots of hours looking on Classic Parker I feel like you guys are family. Thanks.
