As part of getting all of the wiring done in the aft deck hardtop in preparation for installing the headliner, I had to get the radio antennas installed. I want to avoid having holes through the cabintop or deck and finally figured out a way to install these that accomplishes that.

I’ve had this Shakespeare Galaxy marine radio/cell booster antenna for a decade
I bought it back when I thought the boat just needed engines and a paint job. Turns out it needed a bit more than that.
My plan is to use an antenna base that clamps to the stainless safety rail, then run the coaxial cables through the stainless tubing. That means I need to be able to clamp the tubing in place while I drill some holes.

First, I drilled a 7/8″ hole in a 2×4
The handrail tube is 7/8″

Next, I split the 2×4
The saw blade kerf is less than 1/8″.

Tube clamp is ready to go

That works really well

Shop space is tight up at the bow end of the tent

Drilling the final 3/8″ hole

The original safety rail ends came back from the chrome shop


The antenna base is clamped to the tube, with the coax running aft
The cable hole is on the bottom.


Thread the cable through the rail end

Ready for caulk

The stereo antenna is pretty much installed

Back to the ShopSmith for the starboard side

I need two holes on this side for the marine radio and cell booster cables

Harbor Freight die grinder cleans up the edges inside and out

It’s more challenging running two cables through the tube

Looks good

That’s a wrap for now
I plan on opening a tube of caulk and installing all of the safety rails at the same time. So I’ll leave the aft ends loose for now.
