Previous comments restrict the issue to microwave frequencies and a double-ridge guide horn.
I believe this issue first came up when transitioning from dipoles to higher gain antennas below 1 GHz, such as log-periodic arrays. The same concept applies to LPAs.

If yes, can you please get me the reference section in FCC Part15 or ANSI std or somewhere else? Thanks a lot in advance!
