I own a 2003 38 Open and the antenna on the boat looks very similar.. See attachments. Not sure why you want to change the antenna as it supports Digital Over the Air TV. I upgraded my TV's several years ago w/LCD's and I get very good reception on over the air digital channels. On the 38 there is a power supply supporting the antenna located behind the shore power panel ... Hope this helps..

Thanks for the response maybe its the TV I have a 13" Sharp looks old lol The boat is an 88 not sure if it came from factory

don't forget the signal going out now is a digital signal, so you need a digital antenna.  Now if you haven't upgraded your TV's, you'll have a problem.  You can solve it one of 2 ways, go buy digital TV's , or go buy convertors for the Antenna, which will change the digital TV signal to analog.  That's the route I took, and I bought a couple off ebay rather cheaply, and run off 12 volt power like my tv.  That said, I think I should have upgraded my TV's !!  The digital signal is much better.
