Wow... looks like you're in a really deep valley, as only NBC is "line of sight" (that's what those "LOS" notations mean.) All your other networks affiliates are shadowed by at least two ridges (the "2-edge" notations). You need a deep-fringe solution, which involves a pre-amplifier and separate antennas for VHF and UHF:
• Winegard YA-1713 VHF antenna, aimed due east at WBNG channel 12 in Binghamton, to capture CBS. You may also be able to pick up Fox affiliate WICZ channel 40 (operates on channnel 8) with this antenna.
• Antennas Direct 91XG UHF antenna, aimed toward the west-northwest toward Cornell, to capture WETM channel 18 (NBC), WENY channel 36 (ABC), WSKG channel 46 (PBS – shows up as WSKA channel 30 in the TVFool report), and WYDC channel 48 (Fox).
• A VHF/UHF combiner, such as a Holland, TruSpec or Pico Macom UVSJ.
• A Winegard HDP-269 pre-amplifier.
Don't substitute or omit any components. The separate antennas give you the ability to aim in both directions without having to use a rotator. Your NBC station is both strong and nearby, so it will overload all other pre-amps besides this one, but you still need the boost for the other, much weaker stations. The UVSJ combines the two antennas' signals onto one cable, which then feeds the pre-amplifier input. The pre-amp is powered through the coaxial downlead from the amp output to a power injector, which can be located either behind a single TV, or just ahead of a splitter mounted indoors if multiple TVs are to be connected to the antennas.
Aside from the four other stations in the report's green band – most of which are likely to offer religious or Spanish-language broadcasts, if they're on the air at all – the other stations shown are likely to be far too weak to be received any more often than intermittently, at best.
