multi-directional TV antennasĪntennas described as "directional" are designed to receive signals from one direction. Antenna elements are based on the size of the waves they're designed to receive, and VHF frequencies are lower so the waves are longer, requiring a larger antenna surface to receive them. What's the difference between UHF and VHF antennas? Mainly size. We carry several models that cover the entire VHF/UHF range, channels 2-51. If some of the local stations you want to receive are below 14 - especially channels 2-6 - you'll need a VHF/UHF antenna. There are nearly 1,800 full-power TV stations across the U.S., including 1300+ UHF, around 450 high-band VHF, and fewer than 50 low-band VHF. The VHF channel range is 2-13 - "low-band" VHF is channels 2-6 "high-band" VHF is channels 7-13. Like analog signals, digital TV signals can be broadcast over two different frequency ranges: VHF (Very High Frequency) and UHF (Ultra High Frequency). So we recommend purchasing your TV antenna from a dealer who offers no-hassle returns with a money-back guarantee. Keep in mind that even in the same neighborhood reception conditions can vary from house to house. The information below will help you zero in on the type(s) of antenna that should work best for you. TV signals actually bend a bit in the atmosphere, which can extend reception range beyond the usual line-of-sight limit of 70 miles. This is where careful HD antenna selection and installation become essential. If you live within a few miles of the transmitter, and the signal path is relatively unobstructed, you may be able to get solid reception using a small indoor antenna.īut as you move farther away, getting usable signal strength becomes trickier. The main factors determining reception are the distance and direction from the TV station transmitters to your home. The transmitter's power and the height of its tower also matter. No one antenna or antenna type will deliver excellent TV reception in every location. Now that you know the direction and signal quality of the local TV stations you can receive, let's see which type of TV antenna will work best for you. To see where the transmitters are located use the TV Fool site. Each station has a color-coded indicator showing its signal strength. Once you enter your address, you'll see a list of local stations. The quick, easy way to get information that's specific to your address is to use the FCC's DTV Reception Map tool. In addition to distance and direction to the transmitters, you need to be aware of obstacles like mountains and tall buildings. So, the first step is to locate the transmitters for your local stations. Mountains or tall buildings between the transmitter tower(s) and your home can also cause reception problems. TV signal transmission is "line of sight." Getting reliable reception beyond the curvature of the earth (roughly 70 miles) is difficult. ![]() Over-the-air TV signals provide excellent picture quality: Cable and satellite providers offer hundreds of channels, but they employ data compression or other techniques that compromise picture quality.TV households can receive at least one local station 89% can get five or more stations.
