Even though the installation was a nightmare see:
http://forum.tvfool.com/showpost.php...87&postcount=4 Reception with the antenna up top, even though much lower than I wished, has vastly improved. I had doubts regarding the accuracy of my (compass free) eyeball pointing of the antenna/rotor due north but setting the rotor to the TV fool magnetic compass points seem REALLY spot on. At night I can reach the Cleveland channels that are far out of range & during the day many Detroit ones are solidly received. Oddly the 2 channels that are shaky (for the most part) are the 2 strongest ones 7 (WXYZ) & 4 (WDIV), I see the Adjacent channel warning, which I assume is 2.1 (7 real) (WJBK) but this channel is very low power & I didn't honestly expect to receive it at all, but now is being received very strongly, even (sometimes) during the day. I don't know it there is anything I can do about it & this is mostly a concern as the sub channel 4.2 (THIS TV) is one of my favorites. Lucky during my 3rd shift early AM viewing prime time so far this is MUCH less an issue as you would expect, I was able the to watch several hours of THIS TV programming last night w/o a glitch but this was only the first full night of viewing so I hope it wasn't a fluke. I tried using the attenuator thinking that since 7 (WXYZ) & 4 (WDIV) are so high power & now are being pulled in stronger on the roof that they might be over driving but it didn't help.
The antenna is not grounded so I'm thinking of using the:
