Well, we don't *need* DC-to-daylight access to those antennas, just the 
bands we're actually using, so it just makes sense to open up the other 
bands to other services as required and tap off just the 
bands/frequencies we're equipped for.  Ron's right, those ports are 
*valuable*.  ;-)

Now, that must be *some* multiplexer they have on each port, if a number 
of different transceivers are sharing the port -- keeping the ham 
transmitters from desensing the other receivers must have taken some 
engineering.  Quite impressive, if you think about it.
