Sort of. I've found that the C3-SS is much more sensitive to just about
anything in close proximity. Tom says that being up higher should get rid of
the problem but sometimes you don't have that option. Even seemingly
non-conductive stuff like roofing materials seems to affect it. The only
thing you can do is to keep the built-in ATU turned on so it'll flatten the
coax. Not the most elegant of solutions but it works.
