anyone here ever use #10 house wire (singe insulated strand, the kind that goes inside armored cable) as twisted pair? seems like it would be in the high 90s impedance, and easier for me to get than

Probably really dependent on the insulation and such things as how tightly twisted it is. AWG10 is almost always stranded, which makes figuring out the conductor diameter a bit tricky (since AWG is t

No comment on the impedance. But while you're thinking about this, remember that mismatch contributes relatively little additional loss to the total picture until there's a LOT of mismatch. See the A

I agree that the 75 ohm kw balanced line is impossible to find. I've looked and looked with no results. However, you can go ahead and use 300 ohm, 450 ohm or 600 ohm balanced line and have negligible
