And... you forgot to mention one other thing to our mis-informed friend...
Carriers MAY share towers (forced to by NIMBYs, etc) in some locations.
But they DO NOT share antennas/electronics.
Andrew: Look at the bottom of a tower with 2-3 or even more antenna 'platforms' on it
Notice the multiple equipment cabinets and/or small buildings? Each carrier on the
tower has completely separate radios and antennas.
Lots of ideal spots will sometimes have 'antenna farms' - multiple antenna structures
close to each other. Each carrier built their own...
