If it is not empty it might have some microwave stuff or possibly a
Rubidium frequency standard that you could use to calibrate frequency

It is not empty, look at the next pictures, they show "something".

Ah, okay, my telecom guy says they are cavity resonators use to share
signals- probably lower than cell phone frequencies as others have
said (he mentioned 560 MHz or something like that, for which they had
installations).

He doesn't think there is much market for that stuff these days
because cell phones have replaced most of the 2-way radios.
