You can purchase heat shrink with the hot melt glue on the inside.
When you shrink the tube (starting at the center and working out) the
hot melt glue coats everything and the tube is much stronger than the
stuff you get at radio shack.


Roger,

Would you be so kind as to provide a source/brand name for the
glue-lined heat shrink tubing you mention above?

It's made by 3M and sold by many electrical supply firms.
The first photo in the link below shows the two types they offer.

The numbers are 800 which is 0.800/0.22", or 20/5/6 mm.
The first number is the diameter "un shrunk" while the second is the
smallest working shrunk diameter.

They also make a 400 which is 0.400/.12", or 10/3.1 mm tube.

These are coated internally with something akin to, or it really is,
hot melt glue.

The price has gone up some, but I think the last I purchased was a bit
over $10 for a 3 foot length of the 800.

why would you be using RG-11? much bigger than RG-6 and will be hard
to terminate...

I'm not. Like you I suggested RG11 might be a bit large.
I tried it here and replaced it with RG-6 for the satellite feed lines
for both the small dish and C-band.

I found it placed too much stress on the LNBs.

However terminating the RG-11 is easy as they make a connector that
slips right on the cable and has an F connector on the other end.
They are more of a "press on" rather than crimp. Work very well.
OTOH they do nothing to relieve the stress imparted to the LNB
connector by the large cable.

I'm planning to run 6 RG11 feeds for my DishTV setup. What is the best
way of making sure the connections are *waterproof* indefinately.

I'm using T&B SNS connectors on the cable and where the connection
meets the LNB, I'm thinking about using some sorta of silicone grease
sealant on the threds, plenty of wrapping with Scotch 88 tape and then
a coat of Skotchcoat.


We used to have some stuff in the Air Force called "F-4 tape" which
worked great for this sort of thing. It's kind of like a putty tape, in
rolls with plastic separating each layer of the tape. You wrap up the
connector like you would with electrical tape, only stretching the tape
a bit as you go. What happens is the tape molds itself together around
the connector and provides a very water-tight seal around the whole tape
job. Not sure if it's available on the civilian market but if so it's a
great item to have handy.


It is made by Pirelli too with a different name. We use it for coax
and for electrical. The connections for sleave pumps 80m down into
a well (= under water) perform - just well ;-)
Never had a coax soaked using this method for over 10 years.

Kind regards, Eike
