Too bad not all installations use good engineering practice. In my 
experience paging system transmitters we're the most likely ones to not 
use isolators or filter cavities. I guess the reason is that they don't 
need to receive, at least not at any frequency their spurs bother, so 
they don't care to spend the money or lose a few tenths of a dB in TX 
signal strength for the benefit of their neighbors on the same mountain 
who do have sensitive receivers.
