Default Thru-Wall Coax Feedthrus

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?

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

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.
