A power antenna is an electrically motorized automotive radio antenna that raises and lowers either manually with a dash-mounted switch or automatically by turning the radio on or off. The automatic kind will also lower when the ignition switch is turned off. Unlike most car antennas adjusted directly by hand, power antennas retract completely ...
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or ...
CEA-909-A is an update to CEA-909 that enables a single coaxial cable to connect smart antennas to smart antenna-capable DTV sets. A weakness of CEA-909 was that it required another control cable in addition to the coaxial cable. This revision was first approved by the Consumer Electronics Association R4 Video Systems Committee on 6 June 2007 ...
Transmitter hunting (also known as T-hunting, fox hunting, bunny hunting, and bunny chasing), is an activity wherein participants use radio direction finding techniques to locate one or more radio transmitters hidden within a designated search area. This activity is most popular among amateur radio enthusiasts, and one organized sport variation ...
LoJack is a stolen vehicle recovery and IoT-connected car system that utilizes GPS and cellular technology to locate users' vehicles, view trip history, see battery levels, track speeding, and maintain vehicle health via a native app. Prior to selling a vehicle, LoJack dealers can use the system to manage and locate inventory, view and manage battery health, and recover stolen inventory.
Transmitter power output. In radio transmission, transmitter power output (TPO) is the actual amount of power (in watts) of radio frequency (RF) energy that a transmitter produces at its output. [1] TPO is a concept related to effective radiated power (ERP), but refers to the power output of a transmitter, without accounting for antenna gain.
