I have done a some amount of comparing the new H20 with my Zenith HD520. Just talking about the OTA section of both units, as I have said before, the H20 is very good on picking up UHF/digital stations some 40 miles away. I have a highly directional uhf antenna (Televes DAT75) and a roter to zero in on 5 HD stations toward Lansing, Mi. 3 stations are northwest and 2 stations are southwest. I split the angle between them (about about 35 degrees I would guess and can pick them all up without moving antenna which shows very good sensitively. Living in the country, I have never had multipath problems. Now, I could do this same thing with the Zenith HD520 but the H20 seems a bit better. But it is certainly no big deal between the 2. Actually, as an overall receiver, I still prefer the Zenith. Now, if we could just get the tuning faster on the H20! By the way, 55 miles distant, the H20 does a 'good to very good' job of picking up the Detroit diigital stations but they are not rock steady 100 percent of the time as the Lansing stations are. The Flint stations come in about as good as the Lansing stations and they are 40 miles away, I would guess. Bottom line, with a good antenna (and a roter, if needed) you can bring in uhf/digital stations some 30-45 miles away just about 99 percent.
