Sandia Aerospace Stand Alone and remote control, low cost Mode-C transponder

STX165 panel mount mode C transponder

STX165R remote mount mode C transponder

For applications where a traditional mode-C transponder is adequate, MGL Avionics offers the Sandia Aerospace transponders. The STX165R transponder can be remotely controlled through MGL G2 EFIS systems, iEFIS systems and the XTreme EFIS.

The STX165 includes a built in altitude encoder, the STX165R obtains the altitude from the connected EFIS system. These transponders are brand new to the market and have just received their FAA certification.

Please note: The STX165 cannot be remotely controlled, it is a full feature, stand-alone transponder. The STX165R is the remote control version. It does not have a panel display and is indended for remote mounting, controlled through an external device such as an EFIS.

These transponders are the current, lowest cost option for a certified mode-c solution on the Planet !

MGL Trig transponder interface

Using the MGL Avionics Trig interface contained in a convenient connector backshell you can connect a Trig Avionics TT21 or TT22 mode a/c/s transponder body to the MGL iEFIS and MX1. Connected to the EFIS via CAN bus the combination is 2020 compliant for the GPS position source in two levels - via the EFIS built in GPS to SIL/SDA 1/1 or by connecting the MGL Avionics SP-12 approved GPS source to SIL/SDA of 2/3.

Note: MGL Avionics South Africa does not resell the Trig transponders, only the interface for them.

Note: You cannot use the Trig transponder control head at the same time as the MGL Trig interface. You can purchase the Trig transponder body without the Trig head for remote applications like this one and save the cost of the head.

Note: A MGL transponder control head will become available for the MGL Avionics T16 transponder. This is also compatible with the MGL Trig interface. The head is in Vega 2.25” format.
