I agree. Further to that, your RG8, RG213, or heaven forbid RG58, has
much more loss per unit length than a good quality RG6. Any signal lost
due to the 75ohm cable will be considerably less than the loss of the
other feedline.

Good quality RG6 makes fantastic scanner coax, but you have to be very
careful with your terminations and adaptors.



Again, it doesn't matter. No scanner is 50 ohms across hundreds of MHZ
anyway, and a 1.5 to 1 mismatch is nothing, especially on receive only.
