The TIGER - Unwin transmitters have been modified to be a Stereo version. 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°.
