That is likely a stormscope antenna. Douglas L. Dodson, Jr. Glasair II-S FT Flight Test Engineer, CFI-A,G -----Original Message----- From: owner-avionics-list-server@matronics.com [mailto:owner-avionics-list-server@matronics.com]On Behalf Of bakerocb@cox.net Sent: Thursday, March 01, 2007 8:11 PM 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.

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.

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.
