I think for a mobile installation you need to use the coax seal.  I never
use electrical tape for the seal.  I like to use a small drop of coax grease
on the outer threads, then tighten firmly and wrap with the coax seal tape.
If possible I would avoid using the barrel to lengthen the coax.  If it's
not too much trouble you should use a continuous run but if the barrel will
be inside the RV then the barrel should be okay.

When I use it, I put the coax seal on first or only. Honestly though, I have

a couple that I put nothing on to seal them over the years and it's never
been a problem so long as the connection is good and tight. Especially if
it's like the base antennas with the sleeve over the connector anyway, but
my ringo ranger had nothing over the pl259 and I never had a problem. I
don't know if my A99 one is sealed or not come to think and that one's good,

I know the old one was sealed because I did it myself but I'm not sure about

after I replaced it 7 years ago if I resealed it or not. I didn't do the
work that time, the first time I did most of it myself.
