I know of two good ways to quiet noisy mast wires. 1. If the wires are already in the mast, you can pick up some foam plumbing pipe insulation (usually about four feet long and hollow in the middle -- very light) and slide it up the wires into the mast. It will probably catch on the ends of screws and such, but a little wiggling should get several four foot sections of the stuff up the mast. 2. If you are installing the wires, you can attach nylon ties to the wires and leave the end of the tie sticking out -- don't trim them off. Put a tie every eight to 12 inches so that the untrimmed ends of the ties stick out in a radial pattern inside the mast. The ties will prevent the wires from slapping inside the mast. --------------------------------- Groups are talking. We´re listening. Check out the handy changes to Yahoo! Groups.
