I'm getting 26.5 (0x109) dB for 8-VSB OTA. That's with a highly directional ariel (?? dB), installed in my attic (-10 dB for the celtex), a Winegard low noise ( < 3 dB NF) high gain ( +29 dB IIRC) preamp, ~75 miles from the city, cold night, high pressure, clear skies, full moon so it's too bright to tell if the galactic disc is in the antenna's beam, channel at 177 MHz, .... :) Works OK with occasional uncorrectable error bursts. > It seems to be consistent across all three stations, which are all > coming off the same tower as far as I am aware. > > Generally the video performance is very good but I get occasional > periods of lost packets and slight pixelation in small areas, which is > consistent with being near the lower end of signal strength and losing > a few packets. Watch for the unc and ber counts in femon when you get pixelation.
