Get the end up on the mast
put on by a professional, with one of those epoxy
sealed plugs and soldered properly and it will give you years of trouble free service
. Dont tighten the antenna too much! Pull the cable down the mast
witha messenger, and leave it in there, ie, pull it back up again.
The other end, at the base of the mast must be soldered insitu, this is where most problems occur, make it 150mm longer than needed so you can redo it when the wires corrode! Tape up the join with that self amalging tape to seal it each season.
Use a through deck
connection that can unscrewed for when you lower the mast. really easy to do yourself, but get the top connection done professionally!
