I think I see a balun and the antenna itself is 300 Ω. If the unit at the other end of the cable has both 300 Ω and 75 Ω antenna inputs, it may be worth your while to hunt down some shielded 300 Ω twin lead. Some losses are incurred in the impedance matching balun.

Thanks Eli-
RBRX 1 only has a 75 Ohm input.
My Antennas Direct FM-360 is also 75 Ohm.
I'm afraid dwelling esthetics dictates it's implementation.
BTW, how do you know when you have driven the tuner
"to limit"?
I also noticed that when I amplified the signal the Multipath
increased slightly, whereas the USN reading diminished.
I don't know the significance.
Best, Mats
In a post from 2008 sgmlaw points out the logic of placing
amplification as close to the front end source as possible,
in order to avoid distribution (and other) losses. Connecting
the Sleuth with a short cable near the antenna allowed
attenuation of the amplification with by a not insignificant amount.
