I just installed a dipole antenna using Belden coax 9913-F with pl-259
to so-234(?) connectors. I read online the mention of coax seal to
keep water out. Is this necessary? Is there a common substance around
the house that may work? Thank you.

Seal it with GE RTV Window and Door seal.
It's in a blue caulking-style tube at any Home
Depot for about $3.95. Be sure to use the
CLEAR formula. Do not use the black, grey
or white stuff as the pigments (colors) they used
to shade the RTV in this version is RF-conductive.
Dab it around where the coax goes into the PL-259
and at the juncture of the ring and collar. Also apply
it when it's not going to rain for 24 hours as it takes
that long to dry thru.
