I actually mounted the 91XG with the CM 7777 out in the garage attic at approx. 14' in the air, and am now getting CJNT at 20-21 SNR on the Hauppauge 950Q. All of the other Montreal UHF stations are coming in as well, with the exception of the offline 29.1 - all of the others with a SNR of 23 or greater (CBMT is 27).
The 91XG was able to get 12-CFCF in the house reliably, but not in that position in the attic. I'll live with where it is, since it's getting all UHF stations better than I expected, and eventually build the 2-bay VHF bow-tie antenna (plans by holl_ands, I believe). My only fear is that the direction of the antenna forces me to point through the roof (plywood and asphalt shingles) instead of through the exterior wall, so moisture may play a factor here. It's snowing tonight - would a couple of inches of snow on the roof give the same effect as a wet, soggy roof? I'm just trying to see what the "worst case" signal strength ends up being.
Thank you all for your help.. greatly appreciated!
