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.

a.k.a. 3M Scotch 70 Silicone Fusible Backshell Tape, apparently.

Sounds like good stuff... sort of the high-tech, stable-silicone big
brother of the less-expensive self-amalgamating rubber electrical
tape. Not cheap, though... list price for a 1" by 30' roll is on the
order of $30 in quantity, over $38 in onesies. Ouch.

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

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 threads, plenty of wrapping with Scotch 88 tape and then
a coat of Skotchcoat.

I have had pretty good luck by running a piece of nylon thread along
opposite sides of the connector, taping the thread in place, then coating
the Coax connector with about an eighth of an inch of Hot melt, then when
cool, With a layer or two of electrical tape to protect the Hot melt from
the sun. Thought of using Heat shrink, but it soften the Hot Melt! The
threads can be used to open the melt to make it easy to remove if I need to
access the connector. Some if these connections have gone four years and
look Okay!

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.

threads can be used to open the melt to make it easy to remove if I need to
access the connector. Some if these connections have gone four years and
look Okay!

When you want to remove the cover, just heat a bit and use a box
cutter, or sharp knife to cut it away. (wear leather gloves)

The stuff is made by 3M in two sizes that I've seen
800 IMCSN .80"/.22" 20/5.6 mm
and .400 IMCSN .40"/.12" 10/3.1 mm
It's a tad over a dollar a foot.

Also Times wire packages a piece with their N connectors.

I have some photos of both sizes of tubing as well as the connector
and I have one splice that has been taken apart.

I cut the splice out of the line as I though there was a problem with
it, which there was, but it was the last thing I expected. It turns
out the barrel connector had shorted and the other connectors were
still good, or would have been if I hadn't cut them out.

I'll try and get some shots up on my web page Monday or tuesday.
My home page is www.rogerhalstead.com and the URL for the coax splices
and heat shrink tubing *will* be
http://www.rogerhalstead.com/ham_files/connectors.htm when it goes up.
As it's past 3:00 AM, I have to create the page, resize the images and
then ftp it up to the server, I think it's gonna wait. To top it off I
have to spend most of tomorrow (Monday) out at the airport, finishing
up a demolition project and then cleaning up... soooo, if my memory
holds that long, I'll try and get the page up Monday evening.

OK, I did get the page up, but only small images. Links to larger 800
X 600 images this evening.

Gentlemen,
As a long time experimentor I have used all of the suggestions given
in this thread. But science has moved on. 'Plastic dip' is now made in
spray form so I use that instead of the semi liguid stuff supplied in
cans which I also use for encapsulating.
The spray form puts a thin film over the joints which can readily be
peeled off
when reworking the joint. The sprayed plastic dip also shrinks
somewhat after application. Cost is around $6 per can of either form
in any hardware store.
Regards
Art

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.

http://www.rogerhalstead.com/ham_files/connectors.htm

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.
