Alexis, I once used a RCS-4 Ameritron Remote Antenna Switch, and it had me chasing my tail. I gave up and stopped using it. It probably didn't have a thing to do with the equipment however.

All I can say about your numbers above, and the questions you note about the bandwidth change is: IMO you are likely dealing with heavy losses somewhere, and CMC could be part of the issues you need to be checking.

Noticing big changes in antennas on raising is not generally a good sign, and not all antennas respond the same either. I think it is a good idea to match in situ whenever possible, and sometimes being very close to the ground is not productive. I've always considered the Simga4 design type to be very steady in this regard.

However, I had an Sigma4 that on 1 occasion, of numerous installs over time, where I discovered the gamma was not positioned precisely between the two radials as it should be. The skewing in that case was about 1/2" or less off center. I assumed it got bumped at some point and I had a real problem tuning the antenna, and then seeing the match change on raising. Something at least to check out. I think I've already posted something about this experience sometime back.
