The "ex-band" encompasses part of the old "police band".

I gather that this was one-way (simplex) with return calls being  
effected from a "police call box".

Even as late as the 1960s, there was a tower at the West Los Angeles  
regional police station, next to the county superior courthouse, and  
across from the WLA regional library, and which broadcast in the  
police band.

This was made famous, or infamous, in the film-noir "Mildred Pierce",  
where they identified the (police) station by its KMA-number during  
calls to murder scenes which were supposedly in Malibu.

I strongly suspect this "station" was inactive after the 1950s,  
although the tower remained for quite a while thereafter.
