Update on Washington DC Television Transition: OTA channel assignments

The information below is what the FCC has for the Washington DMA. If you ask most television stations what their frequency is, they don't have a clue. The FCC also says I should receive all of these stations at my house. These stations are VHF and UHF, so your standard TV antenna should work fine (see study). I contend there is no such thing as a "high-def" antenna. Radio waves are radio waves. The frequency is the same. If you're experiencing multi-path errors, then try using a directional antenna. (How do you determine if you're reception problems are multi-path errors? Well in the analog days, multi-path was ghosting. Generally, you should be getting good reception because you're close, but you can't lock on.)

If you're wondering why you can't receive a station, here's a study by the FCC on DTV reception in Washington, DC. If you have a hundred thousand dollars in equipment you'll be able to replicate their results: You're less likely to receive DTV signals than you were analog signals. You can improve your chances with a thirty-foot mast.

For the tripod-mounted, indoor-type antennas, SPI was 86% for WUSA and 84% for WRC when the better of either the bowtie antenna or the Silver Sensor directional antenna was used. These SPIs for the combined indoor antenna types exceed the above values for mast-mounted antenna reception computed in the 1998 study.
