"a Centris study released in February 2008 revealed "serious 'gaps' in digital TV signal coverage across the country "when taking into account 'outdoor receiving antenna sensitivity and multipath interference.'" As a result, the Centris study states, "certain households - for example: those that are not elevated; are surrounded by trees; or have set-top antennas instead of roof-top antennas; among other factors - are at higher risk of having limited or no signal coverage. Centris surveys reveal that 75% or more of over-the-air households have only set-top antennas."[3]"

Um...a fool coulda stated that. It does NOT state that those people will have no TV. Naturally, someone running cheap rabbit ears will have a higher risk of losing signal than someone with a wide band, full sized rooftop antenna. Naturally someone in a geographic bowl has a higher risk of losing signal over someone on a hill. So? If they both DO get signal, then they both get the exact SAME signal.
