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

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.
