When I put it at 40 feet, the NM is -2.8dB, WNAC is at 1.7 and WPRI is at 1.2. Is noise margin the same thing as signal noise ratio? Also, It seems like on my TV fool report that I can get WCVB better than it suggests since the SNR is 29 when near the window. Not sure what to take from all of this.
