Greg:
For ten years before I installed my tower in the back yard, I had a bunch
of wire antennas strung through the trees. The coax to these antennas exited
my shack through the crawl space underneath via a 4-inch hole I cut into the
header board with a hole saw.
I then installed a drier vent assembly (for a clothes drier exhaust) into
the hole and ran the coaxes out that way. I used a large piece of fiberglass
insulation to plug up the hole, yet allow for future additions to the antenna
farm. Worked great, lasted a long time and was cheap.
The trick is to ensure that the conduit opening points downward so that
the insulation doesn't get rained on.

Greg,
I have had great luck with Copper Scrubbies. I buy them in the Kitchen
department at Wal*Mart in packs of 4. I stuff them into the open ends of my
conduit (2 inch) and can easily remove and reinsert them. They keep the
critters out (and I have lots around) I think because they don't like to chew
on metal, and still allow the conduit to breathe.

I'm wondering how other seal conduit runs out to the towers.
I installed 4 inch non-perforated drain tile to both my towers.MUCH MUCH
cheaper then pvc conduit.I want to seal the ends up in a way to keep
critters out.I'm not too worried about water because I believe it is
impossible to keep water out no matter what you do.I use cables cables that
are direct burial..I also want to allow it to "breathe".I thought of used
that foam stuff that you can use to seal up cracks around your windows and
such.Then I'd drill a small 3/16 maybe hole behind the plug to allow it to
breathe.Plus this way when I get a stupid idea to install another antenna
all I need to do is get the stuff out which is easy.
I'm always open to other ideas. Gregg K9KL
