I thought I was pushing my luck with almost 9 feet of mast and the GM above the rotor. After watching in some severe weather I feel a little more comfortable so long as my 1923 chimney holds up. I think that's my weakest link but then again, mother nature has a way of finding weakness we overlook at times. I've also put the GM through a range of VSWR test by placing it in locations one would think cause detrimental interaction. This antenna seems to keep its low VSWR almost regardless of how you mount it (within limits) For example, on a 5 foot mast on the ground has the same VSWR it has installed on the roof.

This was within 15 feet of an aluminum sided building too. If you put this antenna up and don't get a flat VSWR right out of the box, something is seriously wrong because it takes a low to mess this match up. Keep in mind, many of these things mentioned can poorly impact its radiation pattern and performance even though it may not be so evident in the match.
