would you be able to find out if the Phillips (letters missing) 2510/27 is actually 50db? There are subchannels of the new digital TV in the UHF range (they are using the spaces from channel 14 to channel 50) that I'm not getting. There are also 2 mains that I'm not getting, not to speak of the subs. I'm thinking either the 50db units, or a amp box by motorola or switchcraft (#7777) but I don't want to saturate or distort the inputs, maybe a vaariable input? I'm guessing it's all F connectors.
