Default Indoor FM boost with no cables?

Hello. I've seen many 'boosters' for radio reception, none of which do what
I'm hoping for, so either my aim is foolish beyond imagining, or really
interesting. Please tell me which.

I hope to boost the incoming signal to override the ocal RF mush from nearby
flats, and to do this for a portable receiver so I want no cables attached to
it at all. I have considered two possible ideas:
1. Take a feed from my existing outdoor antenna and make a dipole indoors,
for passive re-radiation of whatever the outdoor one picks up.
2. Same thing, but using a small preamp I built once (uses a MAR6 I think,
about 22dB gain), but instead of feeding the RF input on a tuner as usual,
drive a small dipole to allow any small receiver with a whip or a wire to get
enough of the externally derived signal to beat the indoor mush.

(I think that feedback would be a problem, with any serious power, but
perhaps something as small as the MAR6-based booster I mentioned might work
ok, given that the outdoor antenna is several tens of feet distant. Anyway,
that's the idea, and if it, or something I haven't thought of or mentioned at
all will solve this for me, please tell me. Alternatively, please tell me
what is the impossible obstacle to this notion...)

Crow.
