Those  horns would be short hops to banks, insurance companies, and the  like,

Not unless you are speaking of the small 18" diameter small stuff.
 
The large cornicopia horns and similar ilk were first used for the TD-2  
radio used by AT&T stateside for about 3.9 to 4.2 gHz. service. We used  typically 
six channels (600 voice or one 6 mHz video channel), per radio  channel. 
These were radio hops of 25 to 30 miles with horizontal and vertical  
polarization, sow with proper multiplexing you could get up to 12 channels on a  radio 
link.
 
I forget how many channel between the bandwidth extremes we could stack in  
there.
 
Long time ago.
