Scanners are notorious for a lack of front end selectivity and
resultant high intermodulation products / noise.

Sometimes they depend on narrow band antennas to supplement their
meagre front end selectivity.

In the absense of external front end selectivity, you may find that
the realisable sensitivity is quite a deal higher (tens of dB worse)
than specification, depending on your own RF environment.
