I had no problem receiving all of my local OTA digital channels with the Voom Motorola DSR550. Connecting the same OTA antenna cable to either a D* H10 or an E* 811 (I have both services at the moment) results in much lower signal strength. Signal strengths of 90 to 100% on the Voom box translate into signal strengths of 30 to 60% on either the H10 or the 811. I read somewhere on this board that the DSR550 actually powered the antenna Voom provided in their install. That post claimed that an alternate amplifier would be needed in order to use the same antenna successfully on another system. Thought this doesn't make sense to me, I'm curious to know if this is the case. Anybody else run into problems connecting their OTA antenna to an E* or D* box?
