Gentlemen,
I want to install a circular TV antenna on the mast of my C36 Mk11 just above the Radome about halfway up the mast near the spreader.
While it could go on the masthead, this is adequate for reception in the area I sail. ( I currently pull the antenna up a flag halyard.)
I note in a C34 Charleston Spar Manual that there are 2 conduits in the mast, one to the top and one halfway but I am not sure where the latter starts and ends and which side is which. (I will contact them for the drawings of the C36 spar).

Also, its pretty tight at the base of the mast and I guess I will have to carefully drill another hole to catch a feeder line and haul out the coax cable.

While I am happy to go up the mast with all the tools and install it myself I would be grateful if any of you good folk have any tips.

Alternatively I may resign myself to paying a professional a days wages to do the job.
Many thanks in anticipation.
