Just one comment, Radar uses a much higher frequency than Comm or Nav, etc.
So while the metal flake paint messes with radar returns due to it's
"reflectivity". I doubt it would do much to the comm antenna

There are also dielectric loss issues at higher frequencies.
I think we've tested coatings and materials that had no metal
content but offered unacceptable reflections and/or refraction of the
radar signals. Except for these isolated examples I think you're correct
in that the lower frequency systems are less vulnerable
to coatings that might affect microwaves.
