Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
CEA-909 is the ANSI standard for 8VSB/ATSC smart antennas.The basic concept is that the smart antenna either physically rotates toward the signal, or is stationary, but has elements pointed in different directions and uses only those elements that maximize the received signal.
Canada had a similar analog TV termination date set to September 1, 2011 (except in some remote northern regions). [citation needed] It was feared that the US switch-off would cause millions of non-cable- and non-satellite-connected TV sets to "go dark". Viewers who did not upgrade, either to a television with a digital tuner or a set-top box ...
8-Port TV Distribution Amplifier. For households with multiple TVs, the Antennas Direct 8-Port TV Distribution Amplifier can split a signal with no noticeable impact on signal quality.
A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...
OTA antennas are digital receivers that pick up signals broadcast by local TV towers, allowing you to watch local programming without cable. These antennas cost anywhere from $15 to $50.
