1. The antenna was a long tubular one, I can't even remember the name, it works great, but I had to arrange it in such a way that was not as pleasing as I would like, did not want to have to run it to the attic ( I am selling it for $30 !!
2. Reception is the same, but I can keep the Silver Sensor antenna behind the TV and out of the way without having to run an extra line to the attic.
3. There are no hills, It is somewhat a tree filled area though, I live in the town of Lockport which is pretty suburban even on the borderline rural.
4. I have been able to point the antenna in many ways to keep the signal in, I think I have it set up on a shelf behind the TV about 4' from the floor facing South/ Southwest.
