At the risk of seeming a shill for Magnum Dynalab, you should get their MD
205 "signal sleuth".

I just love audiophile hardware.
This one is only $440. Ouch.

Chuckle:
"signal amplification variable from -10dB thru +30dB (30 times
to gain) to bring weak stations to full quieting* and tame
strong, harsh, local signals"
30dB power gain is 1000 times.

I would love to see the shape factor of their filter that's 400Khz
wide (so that it passes HDRadio signals), yet is -70dB down on the
adjacent channel, which is 0 KHz away. (US FM stations are on 200KHz
channel spacing will allocations on alternating 400KHz slots).

It doesn't just boost the signal. It cleans it up.

Not really, but it seems like it would help get rid of overload from
excessively strong nearby TV signals. Just an FM band pass filter
would probably do most of the heavy lifting.

Remember to put ferrite
chokes on the AC power cords of all your FM equipment (and possibly the
audio cables), so the good work done by the MD 205 won't be undone by direct
RF entry.

That does no good with todays plastic case, unshielded receivers. Some
work better with no antenna attached. The FCC Part 15 conducted
radiation filter found the AC power cable usually does a great job of
blocking such RF pickup.
