Q: I live in Plano, and have a new HDTV with a built in ATSC tuner. I also purchased two DTV converters for my older analog TVs. All three TVs are hooked to antennas, and are strictly receiving over the air broadcasts only (no cable or dish services). I receive 30 rock solid signals on all 3 TVs, including stations from Sherman and Oklahoma. The only digital station that I cannot lock onto is WFAA. I have spoken to others who are having the same problem. If I move the antenna around, I can somewhat receive WFAA, but it doesn't lock, and is unwatchable. Any advice?A: Good to hear from you. At this time, WFAA is the only local station broadcasting its digital signal on a VHF frequency (Channel 9). All other local stations are on UHF (channels 14 and higher), which are easier to receive with smaller antennas. Make sure that your antenna is rated for both UHF and VHF reception and is aimed at Cedar Hill, where all the local stations have their transmitters. As a test, connect a digital TV set directly to an antenna, bypassing any signal splitters, and see if you can receive WFAA. If that test is successful, it's likely that an antenna booster (RF amplifier) will be needed to increase the signal level enough to counter the signal loss that occurs whenever you split an antenna feed multiple times. You should know that two stations that currently transmit their digital signals on UHF -- Channels 11 and 52 -- will be moving those signals to VHF channels next February so you'll want to make sure that you have adequate reception on VHF before then.
