One additional point.

On my bookshelf a

_Antennas_ (Kraus), _Physical Design of Yagi Antennas_ (Leeson), _HF
Antennas for All Locations_ (Moxon), _Antennas and Transmission Lines_
(Kuecken), _Radiowave Propagation and Antennas for Personal
Communcations_ (Siwak), _Lines, Waves, and Antennas_ (Brown et al),
_Antennas and Waves_ (King and Harrison), _Transmission Lines, Antennas,
and Wave Guides_ (King et al), _Directional Broadcast Antennas_
(Layton), and _TV and Other Receiving Antennas_ (Bailey).

Other books have "Antennas" in chapter titles, e.g., in _Antenna
Engineering Handbook_ (Johnson) we find "Loop Antennas", "Small
Antennas", "Microstrip Antennas", "Leaky-Wave Antennas", and so forth.

I don't have a single text with "Antennae" in the title, chapter
heading, or body. But then, I don't have any entomology texts at all.

If "antennae" is to be the "correct" plural for radio antenna, an awful
lot of very well known authors and publishers need to be made aware of it.
