Bob,
This is a very interesting question. In our VHF contesting mountain top setting we are running stacked beams with 1 KW amps within 100 feet of each other. Sometimes makes for challenges in terms of interference but nothing has gotten blown up.
I would be curious to know what others have found with SDR's for the downlink. They do seems a little more prone to overload problems. We routinely struggle with this on Field Day, especially between the 6m and satellite station. Again nothing gets destroyed but the station to station interference can be quite severe.

My neighbor has a HF vertical (10/15/20 meter trap) that is about 30 feet from my 2M/70/cm/23cm satellite antennas.
He currently runs 100W and is planning on going to 200W.
Should I be concerned? Will the RF get into my feed lines and blow up my rig? Or into my antenna rotor cables and fry my controller?
I am still in construction mode for my satellite ground station.
