I lokked at that and am amazed that a balun can give 5dB gain! What I
would expect is that it could help in reducing the noise floor and
thus sound like you have gain; or provide a better impedence match (at
some frequency(ies) to allow more signal to pass - perhaps. But gain,
nope - I just don't see it unless I have totally missed out on some
part of my radio education.

1) The DX-160 has an Antenna trim knob, so is a preselctor redundant?
2) The 9:1 matching impedance transformer is intriguing, but can they
be found/purchased already built?

Thanks in advance for any input!
