Foam is not a good idea. It can become very difficult to remove.

Best is to use cooper wool. It will not rust nor flake and beasties do
not eat it. The stuff has become hard to find, however.

What do folks use to run coax thru walls ?
I drilled the wall and put in a section of PVC. Ran all the coax and
then filled the PVC with foam in insulation.

Obviously one must fill the extra space with something just to keep bugs,
snakes, and mice from crawling in, but foaming seems sorta final in that,
when one wants to add another coax, the foam will need to be dug out.

I've always just stuffed fiberglas insulation around the coax, but here's
a QUESTION: Would using steel wool (which mice won't chew) affect
currents in and/or on the coax?

Dick, I use a drill followed by a length of coax.

FOAM?? No!

Dick, get a tube of colored caulking compound. I use BROWN for a brown
house [of course]. It makes a weather and insect proof seal and is
easily removed if needed [simply pull the coax and both the coax and
caulking come right out].

Depends--- Choke to R.F.-- NO, Choke to Critters, like
mice, rats and other's, YES! and try S.O.S.- they don't
like soap in their mouths any more than you did as a kid!

Naw, it won't have any noticeable effect on the coax. Sometime ago
some proposed packing steel wool around coax as a common mode choke,
however, Walter Maxwell did some measurements and found that was just
about worthless for choking.

well none of the above stops the Lightning getting into shack and racing
around zapping all and sundry ?
i got a Border Collie here that could get coax into a shack, stop getting
gear zapped , well thats different
heres what I did,
get ur coax from INSIDE TO OUTER WALL,
Terminate it pl259's or whatever, make 2 pieces of ally box section that
will fit together, on the outer side, alighn SO-239's on both ally pieces,
one to collect the coax from INSIDE the shack, and another row to collect
the terminated coax from the antennas,, slide the ally box section together,
and connect centre of SO-239's to SO -239's with BANANA PLUG centres to
ensure a RF connection,
position a Bolt on one side of one ally section, and form a S shaped piece
of ally flat with a hole drilled into it, to take a thin piece of rope,
terminate all so-239s with appropiate coax's ?/ all done, STORM comes, pull
rope, S shape pivots against the bolt in the ally section and UNPLUGS all
antennas together, KEEPING all the nasties OUTSIDE, when storm has gone
plug it back in,
been using one for 15 yrs,

will gladly take some pics if anyone wants

Well, maybe... One of our Dobermans ate a whole box of SOS,
apparently because he LIKED the flavor of the soap!

Dear Mr. Onella: Thanks for the suggestion. I shall ask for it in the
local marine supply store.

Marine supply stores sell bronze wool. I think the boaters use it for
cleaning brass fittings, presumably without scratching them. (I used it
as
EMI packing for some leaky old pull-boxes.)

It may be close enough to copper wool to function the same.
