So I'm guessing you are somewhere in Henrietta? I'm 3 miles further north/east from Pinnacle hill near the bay. I got Buffalo once with an outdoor antenna, mounted about 10' off the ground. That was probably 10 years ago and the tuners are much better. I still have the antenna, but it is uhf only, so not much good after the transition.
Have you tried just plugging the antenna into the tv? If I understand, you are using it to go into a dish box that has an ota tuner.
I'm not familiar with most of the jargon, so some links/explanation would help.
As usual, higher is better, outside is better, better tuner is better.
