Why TWO different antennas?
The AirLink system uses two different frequencies to transmit data back and forth between the computer and the TV. The larger square ‘paddle’ antennas are use to transmit and receive the video and audio data. The audio and video signal is transmitted from the computer side to the TV side of the system. The short ‘pencil’ antennas are used to transmit and receive the keyboard and mouse data from the TV side of the system to the computer side of the system. Data is sent from the keyboard to the IR receiver close to your TV. This is an infrared light beam. The data is then transmitted to the computer, received and processed in the computer and sent back to the TV as video data.
