That is my signal chart. I am interested in the New York channels in the grey area. Am I out of luck?

What would you recommend if I can attempt to get them / if I shouldn't bother?

Do you pick up radio AM/FM reception with the antenna?

Thanks in advance.

I have not looked at all the NY stations, but for those I have identified the co-channel interferer, you would need an antenna with as much as 92 dB of rejection in the direction of the nearby station which is on the same real channel.

If the number was between 20 and 30 dB I would say, 'build a huge experimental / hobby rhombic array'. But I don't think the CIA, NSA, or Men in Black have ever built an antenna with even a fraction of the performance you would need.

And just because the question gets asked, a lot, NO!, an amplifier or filter won't change the laws of physics. A crude analogy would be, you want to find a microphone that will let you record the breath of a sleeping baby a mile away, while the microphone is in a hospital nursery with six crying babies. More precisely, this would be like shining a 5 Watt Christmas tree bulb on a wall in a room lit by a 7,924,465,962 Watt bulb, and trying to find a detector that could tell you if the Christmas bulb was on or off. (Yes, that number is almost 8 Billion. The math is 5 * 10^9.2)

How about this idea, make friends with someone in the NY area if you don't already know people there. Build and operate a HTPC remotely, downloading recorded shows over a VPN. (Most DSL and cable internet links will not have enough bandwidth to stream real time OTA data rates.)

I agree with GUM , The reception in the gray will not happen. The adjacent channel interference and co-channel interference means it will not happen. I also agree with GUM , the answer is NO a 10,000 dB antenna amplifier and magic antenna filters will not bring in the channels in gray , it will not happen. There is this Urban Myth that 10,000 dB antenna amplifiers and magic antenna filters and magic antennas will get Tv reception 1,000,000 miles.

I can tell you this truth , the Tv antenna scams are Full On here in the USA - Canada and most of the rest of the world. You will find the Truth here at the forum of Tvfool.

I knew it would be a shot in the dark. Any recommendations for just the Philly channels?

Would that antenna pick up radio signal as well? AM / FM
Thanks

Winegard HD700R or Antennacraft AC9 pointed toward 342° compass, gets a full line up and FM.

You don't need any amplifiers, there's enough signal power to split 4 ways after a 100' run of coax.


You will need a separate wire or commercial built AM loop... depending on your receiver design.

Here is a way to receive Tv stations some place and receive them any where else ~via~ the internet. http://www.slingmedia.com/go/oem-products
