Nitrogen in horn antennas / waveguides?

I'm working on a project that involves antennas that appear to be
pressurized with nitrogren (approx 10psi). What purpose does this
serve? Does it help with transmission properties, gain, etc? It is
used on an aircraft, if that is a factor.

Thanks in advance!
Dave
