I've thought about something like 
to keep water intrusion out in all but the most extreme conditions. The 
wires can come out of this and go to the hole in the side of the mast. 
I've been thinking about this for years, but still have the leaky gland 
nut (similar to 
through the deck.

I've got the old RG-8U antenna cable, so have a UHF through-bulkhead 
connector https://i.ebayimg.com/images/g/MZwAAOSwA4dWMqDH/s-l640.jpg 
going through the deck with separate wires connected above and below decks.
