Groundplane for transponders

Anyone with depth knowledge of groundplanes for transponders?

- their mission (any theory would be appreciated)?
- required dimension
- required shape (is a cross OK or does it have to circular)
- material (is aluminium tape OK?)
- installation - follow the a/c body, or flat
- how critical is the above (loss of signal strength?)


regards

Search the archives and I think you will find the answers to all your
questions. If I remember correctly, groundplane is supposed to be 5.3 in.
and round. There was a discussion about how size it for a curved surface.
