USE LONG PLASTIC WIRE TIES
RIK, AS TO WHERE IT ENTERS OR EXITS---IF THE MAST HEAD FITTING IS SOLID, YOU WILL PROBABLY HAVE TO DRILL THE RIVETS OUT TO REMOVE THE MAST HEAD THEN DRILL A HOLE NEAR THE TOP FOR THE CABLE TO ENTER. IF THE TOP OF THE MAST IS OPEN-IT IS ONE LESS HOLE TO DRILL. AT THE BOTTOM DRILL ANOTHER HOLE FOR THE COAX TO EXIT. THE COAX SHOULD PASS THROUGH A RUBBER GROMMET IN EACH HOLE. YOU WILL NEED A COAX CONNECTOR AT BOTH ENDS SO YOU CAN REMOVE THE MAST. I RECOMEND YOU PUT A REALLY LONG PLASTIC WIRE TIE ON THE COAX ABOUT EVERY 10-12". LEAVE THE LONG TAIL ON. THIS WILL PREVENT A LOT OF NOISE CAUSED BY THE COAX BANGING THE INSIDE OF THE MAST WHEN THE BOAT ROCKS. OTHERWISE IT WILL BE A REAL SOURCE OF AGRAVATION WHEN SLEEPING ON THE BOAT. GOOD LUCK.
