REFLECTOR: Transponder Antennas

[Craig and Denise Woolston]

Hey all-

 

  John and I have a homemade ¼ wave transponder antenna mounted under the
battery in the nose of the aircraft (completely) inside.  When we first
started flying we got occasional complaints here in SoCal about losing our
beacon.  Now it happens much more frequently and it appears to be when we
are low and in the “ground clutter”.  The frustrating part is the GTX 330
shows a reply light even when ATC says they can’t see the code.  They are
getting a primary but no code.

 

Where have other located their antennas and what type?

 

Has anyone tried the Archer or Advance Electronics Antennas I see in AS?
