In simple terms, the number of channels you can access depends on the signals that are broadcast in your local area. either losing audio and video, or a clear picture without the ghost image. With a digital signal, the symptoms of multipath would be the same as a weak signal, i.e. Once again, this is still viewable, albeit annoying. With an analog signal, this would cause a "ghost" image, which is a faint duplicate of the picture and slightly displaced. With a digital signal that is too weak, the video and audio will cut in and out, or may even disappear altogether.Īnother problem is multipath, where some of the TV signals bounces off structures like tall buildings and arrive slightly later than the signals on a direct path. If a digital signal is slightly weak, it would however still be clear and sharp. Although this is very annoying, the picture can still be seen or perceived. A weak analog signal will, for example, appear as a grainy or snowy picture on the TV screen. You can eliminate the cable and associated subscription costs to enjoy clear reception and more television channels in the comfort of your home living room, or business office reception area.ĭigital TVs have far better clarity and quality than analog TVs, but a weak signal often causes problems with reception. 100 miles radius.Ī TV signal booster and amplifier helps HDTV antenna or standard TV antennas catch many channels that would otherwise be difficult to access and see. New Digital HDTV antennas together with a booster will allow you to watch your favorite cable television shows without having to pay for an ongoing cable subscription.Ī TV antenna booster will give you access to beautifully clear digital television shows for both standard analog and high definition TVs, and will catch all signals within approx. The ATSC 3.0 standard uses the same broadcast frequencies as older versions of ATSC, so the change to that standard doesn’t affect antenna performance.A TV signal booster kit consists of a HDTV antenna plus signal booster that extends TV station broadcast coverage into your home or apartment building by boosting or amplifying existing TV channel signals for clearer audio and video reception.Ĭable antennas have been around for years and have gradually become old technology. NextGen TV or ATSC 3.0–ready: Some antennas carry these labels, but they’re meaningless.Despite some claims of range in the hundreds of miles, the curvature of the Earth limits the range of a TV antenna to about 30 miles on flat ground. Range ratings: We ignore these because range is mostly a matter of the transmitter power and location.Active and passive models: In past tests, we’ve focused on active (amplified) antennas because so many of them cost little or no more than passive models, but for this round, we added several passive models, which often performed as well as or even better than amplified models.Unobtrusive design: You may need to put your antenna in a visible location for the best reception, so it shouldn’t be bulky or ugly.Recent broadcast-transmission changes have made VHF reception more important. Both UHF and VHF: We selected antennas rated for both UHF (channels 14 and above) and at least high-VHF (channels 7 to 13) reception.
