That is likely a stormscope antenna.

Subject: Avionics-List: GPS Antenna?
3/1/2006
Hello Fellow Listers, I am trying to identify an object on the bottom of the
fuselage of a Beech Sierra airplane. It is black plastic about the size of a
cigar box. Embossed on the bottom of the box is an arrow pointing forward
and the letters 3M.
It was described at one time as a GPS antenna, but that does not make much
sense to me. Why would a GPS antenna be on the bottom of the fuselage? I
also am not able to locate any antenna created by 3M.
Any good ideas? Many thanks.

Storm scope antennas are similar to radar dishes and are mounted in the nose
of the plane. ( assuming it isn't single engine prop)

Just did a Google check on 3M Stormscope and you are absolutely right. That
makes me wrong... Twice! The antenna does look a lot like the ADF loop.

Storm scopes work by receiving the radio energy produced by the lightning.
Their antennas emit no energy and thus can be mounted at any RFI quite
location on the airframe.

Thanks Bruce. I had it crossed with WX radar.

I think that needs just a little qualification. Apart from being in a quiet
RFI location it must also be unscreened from a low frequency RF point of
view.
