Trig TC90 Control Head Kit
This innovative use of a control head and separate radio hardware unit (sold separately) provides more installation options, especially when space is at a premium. The control head can be conveniently mounted in a full 57mm (2 Ā¼ā) round hole or even smaller compact mount.
The fitting of the TC90 Control Head is straightforward, and once installed the depth of the radio control head is only 74mm (3ā). In practice, this means that the Trig compact control head can be located in an aircraft instrument panel where a āsingle boxā radio will simply not fit. The compact radio is the perfect communications partner for Trigās transponder Mode S (1090 ES ADS-B Out transponders).
