I'd run lower loss coax for the UHF/VHF than RG-213/U, e.g. LMR400, Belden
9913F, etc, unless the run was less than 25 feet or so, maybe 50ft. For HF
thru 10m (or even 6m) though the RG-213 should be just fine. It may be
cheaper though to just buy a spool of the low loss and use it for the HF too
than to buy two types of coax.

Like the conduit/EMT idea (make'm BIG and run a couple). Also, now's the
time to run a *dedicated* circuit to the shack for a 240V amp supply. if not
needed, it could be connected to 120V instead and the receptacle changed,
but power only a single outlet box w/ it so you can easily switch to 240 V
(duplex vs single breaker and new recepticle).

How many of the eight runs do you use at one time? And I guess the
other runs are spares? Did you consider conduit, so you could replace
cables if required rather than spare runs?

Thanks, jimbo

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?

I did the same thing when I put in the ham shack but I ran 8 runs of
LMR400 cable and also two runs of 8 conductor cable for rotor's.
The outside panel is under the eve of the house and I have another
panel on the wall of the shack.
Tye LMR 400 Ultra Flex is what I used.


I have seven antennas up right now so there is only one spare run and one
spare run for a rotator.
I would guess conduit would be ok but for what I have it's not needed.
I can replace a run here by soldering the center and outer shield to the
new piece and pull it through with out any problems, if the cables had
been run other than the way they are now then conduit would have made
things easier.
