I live about 10 miles from the antenna farm which hosts all seven TV stations that are Xmitting digitally here in Jax.
I installed the SS-1000 in my attic several months ago and was able to receive all stations that were xmitting in the UHF band w/o difficulty...all came in with a signal strength in the high 90's to 100! Two stations (ABC and NBC) have their digital signal in the VHF band and the antenna couldn't pull them in no matter what I did. (I have the feed split between the H-20 and the HDTV.)
Finally, yesterday, I put up the SS-2000 (powered) and everything came in beautifully...all signal strengths were in the high 80's to 100.
When I initally selected the SS-1000, I selected it because of the realtive short distance to the towers and flat terrane. I didn't take into account the fact that several stations were on the VHF band, the number of trees betwen me and the tower, and the influence the attic would have on the VHF signal.
The thing that I really like about the antenna, both SS-1000 and SS-2000, is that it is realitively compact, fits in a small space, and it gets the job done.
If you have any question regarding which to select...go with the SS-2000.
