Generally speaking, you can seal most RF connectors quite nicely with a few
layers of self-amalgamating tape and a layer of PVC tape over the top of
that (to protect from UV).

Many years ago, I picked up a chunk of scrap the local cable TV installer had
left on the ground underneath the utility pole out in front of my house.  It
was a chunk of industrial strength shrink wrap with a layer of goop on the
inside.

Is that stuff available in small quantities?  Would the antenna withstand the
necessary heat?

How do hams seal antenna connectors?

Hi

There are tapes designed for waterproofing things like coax connectors.

It's called 'adhesive lined heatshrink'. Yes, it's available, though a reel
of the Good Stuff (Raychem) costs a small fortune.
They also make custom boots to fit various standard connectors.

Probably best bought as surplus or from a trusted seller who bought reels
from military, autosport or aircraft industries. The short lengths
available on ebay are often inferior grades. A heatshrinking tape is also
available.

Hams tend to use self-amalgamating tape, as Phil recommended.
