An open hardware AzEl rotator system is provided by the SatNOGS Groundstation project. The Alliance Manufacturing Co. of Alliance, Ohio, and the Astatic Corporation of Conneaut, Ohio, manufactured popular radio and TV booster and rotary antenna systems. These products were heavily advertised for radio use in newspapers starting in the early ...
Single ASIP Radio Mount (SARM) is the latest vehicle installation mount developed specifically for RT-1523 or RT-1702 radios. SARM solves space and weight claim issues associated with traditional vehicle installation mounts. SARM operates on 12 or 24 volt allowing installation into any military or civilian vehicle. [10]
In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception , an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver ...
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. [1]

Using a second set of traps, a "triband" antenna can be resonant at three different bands. Given the associated costs of erecting an antenna and rotator system above a tower, the combination of antennas for three amateur bands in one unit is a practical solution. The use of traps is not without disadvantages, however, as they reduce the ...
