The TC20 is the control head of Trig compact transponders (TT21, TT22, TT23 and TT23G). It includes the altitude encoder, saving a separate unit and wiring, and connects to the transponder hardware box installed elsewhere in the aircraft.
It fits a standard 57 mm (2 ¼") instrument hole or a smaller compact cut-out: fittings for both options are supplied. The bright display with adjustable backlight is easy to read in all conditions, and the front panel is splash-proof (open cockpits, seaplanes).
Use it to replace a control head or to complete a remote transponder unit.
