I use a MFJ line noise meter (#852) that receives AM on the 136 MHZ
aircraft band and it's equipped with a homebrew Moxon antenna
and a homebrew step attenuator.  The antenna was described
in QST along with a receiver one can build.  The attenuator has steps
of 6, 10, and 20 DB.  Both the antenna and the antennuator are easy to

IMHO, the antenna that comes with the MFJ is next to worthless
for any serious RFI'ing, but the receiver works great.
