Installation Overview190-01499-02 GTX 3X5 Transponder TSO Installation ManualRev. 9 Page 3-103.7 Transponder AntennaNOTEFor the GTX 345 some types of transponder antennas that utilize thin radiator elements are onlyintended for use at 1030 and 1090 MHz. These types of antennas should be evaluated on a model-by-model basis to determine their suitability for UAT receivers.The GTX 3X5/3X5R must have an UHF antenna. The antennas in table 3-7 are approved for use with theGTX 3X5/3X5R. Other antennas are permitted if they meet these specifications:• Standard 50 ohm vertically polarized antenna with a VSWR < 1.7:1 at 978 MHz and < 1.5:1 at 1090 MHz• TSO-C66( ), TSO-C74( ), or TSO-C112( ) antennas that also meet the VSWR specificationTable 3-7 Acceptable UAT/1090 AntennasManufacturer P/N Model/Description ConnectorType NotesAero Antenna AT130-16 DME Transponder TNC DC GroundedComantCI-100 DME Transponder BNC Open CircuitCI-100-2 DME Transponder TNC Open CircuitCI-105 DME Transponder BNC Open CircuitCI-105-3 DME Transponder BNC Open CircuitCI-105-16 DME Transponder BNC Open CircuitCI-110-40-30 DME Transponder C Open CircuitCI-110-41-30 DME Transponder C DC GroundedCI-110-60-30 DME Transponder C Open CircuitCI-110-61-30 DME Transponder C DC GroundedDayton-Granger L10-611-( ) L-Band Blade C DC GroundedGarmin590-0052 or013-00219-00 A-40 TNC Open Circuit590-0051 or013-00174-00 A-41 TNC DC Grounded
