Additional items you will require, but which are not in the TY91 package, include:
-Antenna and fixing hardware. The TY91 is compatible with any standard 50 ohm vertically polarised antenna with a VSWR better than 2.5:1.
-Cables. You need to supply and fabricate all required cables.
-Fixings. To secure the VHF radio tray to the airframe you will need at least 3 flat head screws and three self-locking nuts. If the aircraft does not have existing mounting provisions you may need to fabricate additional brackets to support the VHF radio tray.


The TY91 Trig radio two place intercom is optimised for use with standard aviation headsets – a number of adjustments allow the radio to be used successfully in noisy aircraft. The TY91 also has a built in speaker amplifier that can drive an external speaker, this is preferred by some glider pilots.

The innovative use of a control head and separate radio hardware unit provides more installation options, especially when space is at a premium. The control head can be conveniently mounted in a full 57mm (2 ¼�) round hole or even smaller compact mount. Fitting is straightforward, and once installed the depth of the radio control head is only 74mm (3�). In practice this means that the Trig TY91 and TY92 control head can be located in an aircraft instrument panel where a ‘single box’ radio will simply not fit. A single radio can even be connected to two control heads. This is great for a tandem aircraft in training and flight school use.
