About two years a local provider installed a (I believe) Canopy system on top of the grain elevator about 20 feet horizontally from one of our remote receiver antennas on 2M. We were subjected to 10+db of desensing from it. In this case, were fortunate enough to be able to move our antenna to another mounting point about 80 feet away from the Canopy equipment. The physical separation totally solved the problem.
I believe that much of the problem is just plain <digital broadband> junk, not necessarily coming from the RF gear itself, but the support circuitry. Unfortunately, in many cases, the two are so close to each other within the antenna enclosure that it's a moot point... As others have said, any shielding and separation from your 2M antenna you can do will help. Laryn K8TVZ
