I have a Hughes E86 and an RCA DTC-100 hooked up to the same TV and antenna. The E86 is hooked up through the component connection and the RCA through the RGB port. This has probably been dicsussed before, but from my observations the DTC100 OTA substantially outperforms the E86. The signal strength has much less fluctuation and when the antenna is pionted at my "sweet spot" the RCA gets reception on 2 more digital channels then the E86. I dont know why this is the case, but I thought I would pass my findings along.
