For the insulation, you can buy extruded foam that is soft and easy to cut
in 3 to 5 inch diameter. 6 feet of the stuff costs 3 or 4 bucks. Drill
holes slightly smaller than the coax you are running through it, then slice
it so that it creates an open side.
Lay your cable into it through the slice along the length of it, and slide
it all into the entrance pipe. It makes a weatherproof seal and is cheap.
Smaller cables such as rg58 and rotor cable doesn't need a hole drilled at
all, just lay it in a slit made lengthways and the foam conforms to the
cables diameter and seals perfectly.
I suggest using the 3 or 4 inch diameter stuff as it's easier to work with
when you have 8 or 10 coax runs passing through it.
Put just a few drops of vegetable oil on the coax where it slides into the
foam and it will be very easy to slide the coax in and out when you want to
add additional runs.
I used a dryer entrance hose bracket which has a nice rain shield and is
cheap and available.
The extruded foam is a Wal Mart type item, sold in the toy section. Look
near the pool supplies, they are called 'noodles' and are sold as floats
for kids (and adults) to keep them floating in the pool. Some have holes in
them already, others are solid (without holes).
Good Luck to all.
