Hi all, I want to run a coax into to my house bedroom because I'm disabled.
I recall reading having a short piece of electrical pipe placed through the
wall and sealed after the coax is run. Any other ideas? How much of a tail
should brought into the room?

Anything works if you live in a moderate climate.
Temperatures below freezing point can make problems.
We often have to replace cables which are warm inside
and freezing outside due to water condensate.
The air inside can diffuse through the cable
and cables must prevent air circulation inside by foam filling
and airtight sealed N connectors.
Avoid the use of PL239 by all means, the shielded banana plug
belongs into the thrash bin.
"UHF connector" really means: Unsuited for High Frequencies.

Thanks for the info. A consideration.

You can buy 8 inch long PL-259 barrel connectors on the Internet.

Drill a 5/8 hole through the wall. Put a hardware store 5/8 fender
washer on both sides and caulking under the outside washer.

Seal up the outside cable connector.

Very slight loss at 2M, but negligable below that.

This assumes you have 6 inch walls, if not they are available up to
12 inches long.

If a hole in the outer wall is required ,please ensure that that hole is
drilled in such a way that the conduit pipe is sloping down from inside
to outside to prevent water ingress.

That's a good point, the sort of thing that should be obvious, but
probably gets forgotten.

I was certainly thinking about keeping the cold out. One year I had some
really thick coax, was it RG-17?, coming through a window, didn't want to
leave anything permanent. So all that cold winter the sliding part of the
outer window was partially open, to let the coax through there, and let
the end sit between the two windows. And then when I wanted to use the
antenna, I'd open the inner window and uncoil the bit of coax there, and
connect a piece that went to the rig.

I can't believe I did that, it didn't make things very warm.

The old ARRL Handbooks and Antenna Manuals, for no-modification installs involving double hung
windows, tended to recommend a strip of wood, say 1.5" x 3" x L, where L is the internal dimension,
left to right, of the window frame, or even of the sliding lower section itself, that could be
drilled for passing your antenna cable(s), or maybe just your connector bodies, and designed to
support the lower section of the window is it is dropped down onto it. This piece would typically
be a parallelogram in cross section since the sill generally slopes downward to the outside for
drainage purposes.
