Conduit sounds like a good idea. Would you use metal or PVC?

Ah, shortsighted Jimbo:

Consider these: Damage to one of the coaxes, for example. And what
about rotator cable? Or suppose you get interested
in another band or mode? My advice to people building new homes is
to run conduit wherever you are going to need it,
and make it as big as practical. Then you can pull whatever coax you
need, and upgrade when you feel like it. Or at
least be sure there are accessible pull wires wherever they might be
needed. And coax has a limited lifetime anyway.

I am building a new house. I need two coax runs inside the house
for
two uses. First, for 2 meter, 440 MHz dual band. Second for 2-30
MHz
HF. I am considering using RG213/U for both runs. I know this coax
is
suitable for 440 MHz on runs less than 100 feet. Would there be any
problems for the 2 meter or HF using this coax? Or are there any
suggestions for this project?

Thanks, jimbo

Well, it depends on a lot of factors. You have to use lubricant to pull long runs of PVC insulated coax through PVC
conduit, while metal is slicker, and sometimes it will pull without. Metal will provide little additional shielding,
and bending big stuff requires special benders, while PVC can be formed with a heat gun and a lot of care. For
individual runs, you could use this corrugated PVC stuff which has become very popular for pulling fiber optics, but I
have never seen it in real large sizes, and it will need to be held down more if it has a lot of turns.
