Overview of Transmitter Hardware

  The TIGER Unwin transmitters have been modified to be a Stereo version (Dual beam). Each transmitter consists of sixteen identical units, each delivering 600W of RF energy to a ten element log periodic antenna. The phase delay to each antenna is individually controlled, allowing a very narrow beam (approximately 4°) to be steered across an arc of approximately 60°.
