Hdtv here are a few photos.
Decided to try a rotor with a single 4228.
On Saturday removed the 4228 was playing for a few hours with the 4221 on the rotor. Weird the first thing I noticed is that the 4221 had to point to a different direction to get Nbc and Fox properly.
I dont know why but I had to repoint the antenna more south east compared to the 4228. The Buffalo signals came in about the same as the 4228 with the preamp.
What I did noticed is that the Rochester channles was a bar to 2 lower than the 4228.
Used a dss mount and installed a 1 1/4"ID pole 4' and 1/2 foot tall.
For less load on the rotor and mount I mounted the antenna to the rotor with a light weight 1 1/2"OD stainless steel pole kept it short 42" enough for the antenna.
While I was on the roof could clearly see the Cn tower was a good 15-20' more west about 200 to 205' on a compass. When the antenna is pointed for max signals from Fox and the rest of the Buffalo stations except Nbc its around 180'.
Nbc is a more east. At the current setting I can get Fox at 10 and nbc at 8 to 9 with out moving the rotor. Now I dont have to get on the roof to repeak. I can always set Nbc for 10 and have Fox drop to 8 with a quick press of the remote.
