Trig TY 91 COMMWith 4Foot Harness To Audio Panel

The Trig TY91 is a compact VHF communications radio designed to minimise panel-space requirements while providing modern 8.33 kHz and 25 kHz channel-spacing capability. This configuration is supplied with a 4 ft (approximately 1.2 m) harness for connection to an audio panel.

The TY91 uses a separate control head and radio unit, providing installation flexibility where available panel or equipment-bay space is limited. Its control head is only 74 mm deep, and the radio offers a nominal 6 W output across an 11–33 V supply range.
