[R-390] Slightly OT

This is somewhat topical to impedance matching on a receiver antenna input.
I have a hallifcrafters receiver with a 300 ohm antenna input. I know that
you get maximum energy transfer when your load matches.

I have a 50 ohm antenna and I was looking at a 6:1 balun, but I wonder if I
used a tv balun which is 300 to 75 ohms.

Does anyone know how much of a compromise this is?
