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
