In this case it appears reasonable to expect reception of the first three signals.
A Winegard HD7084P equipped with an Antennas Direct CPA-19 would be my choice of equipment if starting from scratch.
I would like to understand the terrain better. Because an image of the TV Fool report wast posted rather than an active link, it's not possible to click on the station call sign to see the path profile.
Also, can the antenna be mounted higher? Are there trees or buildings in the way of the antenna?
As an aside;
While there are examples of successful reception of signals predicted to be 10 dB lower than the minimum required noise margin, such examples are the exception rather than the norm. I submit that the prediction may have been lower than the actual conditions and I'm confident that the antenna used was not a 'standard dipole' but rather a high gain directional. The statement, "Many Digital Tv tuners are capable of receiving NM (dB) numbers at minus -5 and even minus -10 NM (dB)." demonstrates a lack of understanding of Johnson-Nyquist noise, http://en.wikipedia.org/wiki/Johnson...3Nyquist_noise
and Nyquist Theorem http://en.wikipedia.org/wiki/Nyquist...mpling_theorem http://en.wikipedia.org/wiki/Nyquist_rate
. In fact, typical 'good' tuners need a signal with a Net-NM of +6 to +9 dB because the active electronics in the tuner generate noise in excess of the passive 75Ω antenna system impedance. http://en.allexperts.com/q/Wireless-...rmal-noise.htm
I agree that if the actual NM is negative at the input to the preamp, there is no reason to expect it to magically become positive in the preamp or hardware that follows. Antenna gain is the only gain that can improve signal NM. The gain of the preamp comes at the cost of additional noise. http://forum.tvfool.com/showthread.php?t=109
I would welcome the opportunity to read references that support the claim, "The FCC Federal Communications Commission and Technical Industry standard reference is a , simple dipole , at 30 feet antenna height and 0 NM (dB) with no obstructions between the transmitting antenna and receiving antenna." This claim contradicts the concept of the 'TV Service Contour', http://transition.fcc.gov/Bureaus/MB...ta/readme.html
and the FCC "Tests of ATSC 8-VSB Reception Performance of Consumer Digital Television Receivers", http://www.google.com/url?sa=t&rct=j...nLwagBHwiOmsTw
