[Antennas] Question

[A10382]

Drilling a 1" hole for coax through wood has been a long used practice on
boats.  A 1" forstner bit slices through the hardest wood easily.  1" cork
plugs were typically glued in later if the cable was removed.

For those of you attempting to do this at home.... Use a forstner bit.  It
makes a clean hole without splintering the wood on exit like a 'spade' bit
does.  A good 1" forstner bit typically costs $20 (compared to $3 for a
cheap spade bit), but is worth it's weight in gold   This also reduces
static from your other half. You've all heard " JUST WHAT ARE YOU DOING TO
THE HOUSE?".  Sears used to sell a kit of 6 bits (1/4, 3/8, 1/2, 5/8, 3/4
and 1") for about $50.  Sounds pricey, but once you use one, you will NEVER
go back.

I had used a carbide concrete bit to go through the stucco & lathe on the
outside and then a forstner bit for the plywood and interior for single coax
lines.  It doesn't even get tangled in the insulation!

Personally I like putting a piece of slightly larger PVC in and then running
the coax inside it.  It seems easier to seal the pipe than a cable.  Angle
it down or use an elbow to keep water from following the cable and stuff in
some insulation or screening material to keep insects out.  Forstner bits
can be found up to a 1+3/4".  Beyond that you'll need to use a hole saw.
Larger carbide hole saws are available (even rentable kits used to install
locks).
