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?

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.
