also called VAPOR-BLOC
Try searching on Google for them, should find it
comes in squares about 4 by 5 inches or so.
I don't think they have it at the ham stores.

Best stuff is that black tar like stuff that comes with a paper backing
that
comes with
the bigger connectors called Vapor Wrap by Decibel Products. Put on over
the
entire connector and part of the coax,
then tape it up and black tie wraps to keep the tape on. Good for 10+
years.
It is what the Commercial guys use.

Where might i find it, No local ham stores around here anymore? Is it
available elsewhere.

Thanks

You have to watch some of this stuff as certain brands contain
acetic(?) acid which corrodes copper.

I use a hot glue gun followed by copious layers of self amalgamatind
tape, followed by a couple of layers of standard PVC insulating tape
to prevent UV degradation of the self-amalalg.

It won't hurt a thing as long as it's not contained within a small
area. When contained it'll destroy copper and aluminum. Also it is
water proof, but not moisture proof. (see my earlier post)

Going to that much work I'd just go with flooded heat shrink tube.

I use liquid electrical tape.

I also use flooded heat shrink tubing for a really good seal where
applicable.

I'll second this. I have been using StarBrite Liquid Electrical Tape outdoors for nine years. It
doesn't crack or deteriorate. Connectors have been bright and shiny after three years - (about the
longest that a ham antenna stays of interest). I also use it on the tail light connections on my
boat trailer. Readily available at hardware and home improvement stores.

Go to Radio Shack, they have something called "Coax-Seal" or
something similar, that is a roll of tar-like substance that never
gets hard or dries out. It's always a bit sticky, and works great.



Slick

There is a rubber based sealant labeled for marine use, UV resisitnt,
called GOOP Marine...GOOP is a group of rubber products in a tube
labeled under various names for plumbing, household, automotive
applications...end even rebuilding heels and toes of expensive jogging
shoes ...hence the name SHOE GOO. It is NOT labeled for electronics
applications but it works for my receive antenna-boxes & conectors outside.

It and it's weaker cousin Dow-Corning 3140-RTV sealant, have served me
well in Florida against weather...Both flow and are self leveling till
they solidify overnight so you'll have to build a "mould-wall" of
masking tape or something to control it's flow

3M (and some others) makes a product called Liquid Tape that works
pretty well. West Marine carries the 3M brand and Home Depot
electrical department carries the less pretentious stuff. It's about
$5.75 in a metal can with applicator.

s.t.w.

Not sure what stretch seal is, but I use a couple layers of Scotch LR
followed by more layers of Scotch 88. LR is a rubber strip kind of
tape that sticks to itself, but not your hands, shirt, radio, etc.
This is good enough for above ground locations that do not submerge.
I've peeled the tape off after 4 years in the air and the connection
is dry and shiny.

If it's underground or more wet locations, Bishop Bi Seal is a
professional 'gummy' seal.

I did a bit of searching to see if a retail source was available and
was surprised to find an online catalog version of a vendor I spend
lots of company money at -

I never use RTV on outdoor connections - moisture seeps in, adds to
the acid and rots the connection.

Silicone grease is better, but only if covered by tape or spark plug
boots to keep it on the connection. I only use grease for temporary
setups.
