I have tried with a GE Optima Antenna, and more recently, with a Phillips Silver Sensor. I can't get more than these same 6 channels no matter what I try. I've tried moving the antenna around to face different directions, messing with the rabbit ears on the Optima, etc. I don't get it...I'm basically in the heart of a big city, shouldn't I be able to get more channels than this?
Yes, you should be getting more stations than this - in theory. I don't know how good the ATSC tuner is in the Sceptre X42 TV. It may be poor at handling multipath or fluctuating signals. Also, you are getting only 2 stations, not 6. The sub-channels only count as 1 station. The sub-channels are all part of the data streams from WETA-DT 26 and WDCW-DT 50.
You have a good UHF antenna with the Silver Sensor. Some ATSC tuners allow you to directly enter the digital channel number and will map to the station if it can lock onto whatever it finds. Do you get anything on the signal strength meter for channels 34, 35, 36, 39, 48? (check the 1st post in this thread to see which stations these are under the orange colored column).
The Silver Sensor is moderately directional so find the best clear spot with the least obstruction and aim it towards NW DC. If you have a tall building behind you, you could aim the antenna at that to try to pick up reflected signals. The rabbit ears won't help as those are for longer wavelength VHF channels and all the local stations currently digitally broadcast on UHF channels.
Just how far are you from the broadcast towers in NW DC? Enter your actual street address into antennaweb.org and report back here on the miles and direction. One possibility is that the signal is too strong and you are overloading the Sceptre ATSC receiver. If all else fails, you can get an antenuater at Radio Shack and give that a try.
