DTV countdown: The antenna dilemma

The DTV transition that culminates this Friday, June 12, is putting antennas back in the spotlight. But getting good reception with digital broadcasts can be a tricky business, and there's no one-size-fits-all solution. It depends on your location, the topography around your home, and the distance to the TV station's transmitting towers.
Getting the right antenna for your situation is the first step. (See our previous post, DTV Tips: Choosing and using an antenna for our advice and read the tips and comments from other readers.)

A set-top antenna is the simplest and cheapest solution and should be your first try.
If you're lucky, an indoor antenna will get you all the channels available in your area, with a clear, continuous picture and sound. But it's possible you'll encounter some glitches, because the UHF band is more directional than VHF and more sensitive to obstacles that lie between your antenna and the broadcast tower. About 20 percent of DTV adopters we surveyed said they had trouble with reception.
Here's a recap of our advice on adjusting your antenna.
Make small adjustments and give the tuner in the converter box or DTV a moment to "catch up" and detect the signal. Use the signal-strength meter on the converter box or DTV to see what position is best for a specific station. Moving the antenna even a few inches, or placing it higher up, can help.
Try physically relocating your indoor antenna around various parts of the room—preferably near a window facing the direction of your local TV transmitters. Get some long antenna cables and experiment. In some cities, most or all towers are in the same vicinity. In other areas, or if you live between cities, towers may lie in opposite directions, so you might have to adjust the antenna whenever you switch from one channel to another. Alternatively, you can get an omnidirectional antenna so you don't have to readjust the antenna every time you change channels.
When signals are hard to pull in, a set-top antenna with a built-in signal amplifier may provide better reception. This type of antenna can help if you have a 20-foot or longer cable connecting devices, because signals weaken with distance. It may also help if your particular setup calls for splitting the signal—to simultaneously feed two converter boxes or a TV and a VCR, for examples.
Rather than using a regular cable splitter, you might want to try a powered amplifier with multiple outputs, to avoid losing too much signal strength to each device. But keep in mind that you still have to adjust the antenna for optimal reception. You'll find additional tips from HDTV Tuner Info (http://www.HDTVTunerInfo.com), a web site started by an enthusiast.
There are cases in which an indoor antenna won't be enough. Then it's time for an outdoor model. Again, check the Web sites mentioned above for advice.
