I've lurked around the forums here for some time which helped me choose which service to go with, but had an OTA question that maybe someone can help me with since I couldnt find much on it from searching the forums.

My zip code is 07885 in NJ and whenever I go to antennaweb and enter the address in the section sometimes it tells me I can get the NY affiliate digital channels and sometimes it does not. Yesterday I put my address in and it gave a whole list of stuff from all around the state as far away as NBC broadcasting from Atlantic City. Right now the list of NY digital channels is not included in the listing. Are these glicthes within the web site or something else that I could be doing wrong? I have tried both entering just my zip code as well as the full address both with the same results.

For kicks I had borrowed a Zenith silver sensor antenna from a friend that no longer needed it and hooked it up to my 811 Receiver with and without an amp from Radio Shack that he had. Using the search analog option I was able to pick up channels 2, 5, 7, 11, 25, 31, 41, and 50 with very good reception and 4 and 9 with so-so reception. I was surprised to pick up any of the VHF frequency channels since I thought the Silver Sensor was a UHF only antenna. Is there any reason for that?

Using the DTV search on the 811 I have picked up channels 8, 63, 51 and 56 at different times. All of the reception with the 811 locks in at 49% which seems to be a problem with the 811 from searching around the forums, but I don't understand why would the analog broadcast come in so much stronger than the digital in terms of doing the search for the channels. I don't understand enough about the signals so hopefully someone can point me to a link on some information on it. Also, is this a case where you should try to manually tune the stations from the add DTV function? I plan on using my other receiver to do this, but any advice will be helpful.

I live in a condo and I just want to be fairly certain I can hopefully get these channels from an antenna. I should be able to put an outdoor antenna on my roof, but I need permission from the person I share the place with, others in the unit, as well as the association which is kind of a hassle. If the probability is not high of the OTA working I would prefer to not go through the hassle of getting permission to put the antenna in. Thanks in advance for any help and I appreciate all the info that I get from everyone here.
