whoa nice xilbus! I did a lot of research and that's the antenna I figured would give me the best chances of getting US channels... no luck yet but it's a work in progress!Hey Dascope welcome to the forum. what are the odds of 2 HD stackers in Aylmer? hehe.
Any force applied to the antennas by the wind will be magnified by roughly a factor of 4 based on my guestimate of the lengths involved. I don't believe the top strap/clamp would be able to hold in a strong wind and perhaps if it holds, the mast may bend. Others here may have additional comments since I'm not that into OTA. I just know I wouldn't have that much mast/antenna hanging out that distance from a chimney strap.57, why do you believe I need a stronger or shorter mast? Too much weight on it? If anything I'd have less confidence in the chimney mount than the mast... It seems plenty sturdy?
Does your comment have anything to do with the wind?
I think you're going to have trouble with WNPI unless you can somehow get CHCH into a null on the antenna. (I don't know where that null might be, since I haven't been able to find any antenna pattern data on the web yet for the HD Stacker)oh and as stated in my original post, it's a CM-7778 preamp, not a combiner. I manage to pickup all local stations with the preamp, but I can't aim straight at the towers.
