Successfully ran the VHF coaxial cable through the mast today. The mast conduit had two cables existing, one a two conductor for the anchor light and a three conductor for the steaming and deck light. I tied some old speaker wire I had to the anchor light cable at the top of the mast, pulled the anchor wire out from the bottom of the mast which pulled in my pull wire, attached the VHF coax to the anchor light cable/pull wire and pulled it all back through the mast. Worked pretty easily.
As far as mounting the antenna, there really isn't much room at the top of the mast for the bracket. The upper shrouds go all the way to the top on the flat sides of the mast, the rest of the mast is curved. Decided to drill a hole in the bracket and mount it using the shroud bolt. The bracket is stainless steel and is not responding well to my attempts to drill it. Have a drill press at work so will try Monday.
Recommended drill bits for stainless?.
Haven't drilled the cabin top yet for the pass through fitting....working on my nerves...
Looking to run the inside cable down through the mast support. Tried fishing a heavy line (weed whacker string) but cannot get the turn at the bottom of the support. Will probably disconnect the cabin light and use the wire to pull in a pull wire and pull the antenna wire back with the cabin light wire.
Replaced the four pin deck and mast cable connectors. Be careful tightening the little screw connectors for the wires, I broke one of the screws on the deck fitting with only a little tweaker screw driver, luckily it held the wire.
