Combining TY91 8.33 kHz VHF Radio and TT21 Transponder
The Trig TY91 takes up minimal space and weight. 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 round hole or even smaller compact mount. Fitting is straightforward, and once installed the depth of the radio control head is only 74mm. 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.
Light sport, ultra light, glider and balloon pilots will fit the Trig TY91 radio, this lower powered 6 watt model is ideal for the majority of GA users.
• Low Weight
• 11-33V operation
• Auxiliary Audio Input
• Minimal Panel Space
• Low Power Consumption
• 6 Watts Nominal Output
• 8.33 kHz channel spacing

The TY91 is the perfect comms partner to our TT21 and TT22 Mode S (1090 ES ADS-B Out transponders).
The TY91 is TSO approved for fitting to European and FAA registered aircraft.
TRIG TT21 TRANSPONDER
A two part transponder system, which includes an integrated altitude encoder. In design and technology it is equivalent to the TT22, however, the transmitted output power of the TT21 is lower, qualifying the unit as a Class 2 transponder. Class 2 transponders are suitable for aircraft cruising slower than 175 knots, and operating below 15,000 feet, VFR or IFR. If you NEVER exceed these limits either because the aircraft isn't capable or because you set these limits as an operating limitation, then you can use the less expensive model, the TT21. But if you want to have the option to go above 15K or faster than 175 knots, you need the more expensive one.
