Mast spreaders and antenna wires

[HeadedToTexas]

I am replacing one of the antennas on my mast spreader and I want to understand the wiring before I start taking things apart. Since the cables from the existing GPS antennas do not penetrate the spreaders, the must travel through a chase bored in the spreader to a corresponding port in the mast, true?

The new antenna is a larger diameter SeaWatch 3015, so I will need to move the mount out several inches. Hoping that wire chase in the spreader was bored out far enough by the factory to accommodate bigger or more antennas. Anyone know if it does?

If you can’t work with the current cable chase you could get some Starboard, cut it to match the size of the spreader and then route out a new cable chase in the Starboard.

That makes sense. Good fall back.

About the best you could hope for is to remove the antenna and to pull the few inches you need out of hoped-for slack in the original cable.

Is the spreader wood or fiberglass? If it's 'glass there's a chance the whole thing is hollow and you've got all the room you need. If it's wood it would have been pretty hard to bore a lengthwise hole from the notch in the middle. Maybe they bored it from the outboard end then plugged the end of the hole. That also should give you the length you need. Anyway when you drill the holes for the new mount you'll find out what's in there.

Good question. I’ll find out early next week.
