Product overview
The TX14 uses a built-in four-element antenna array to protect satellite navigation reception. It suppresses interference by forming nulls toward interfering signals and delivers a protected standard RF output to a GNSS receiver. Its intended integration settings include land, marine and airborne platforms, UAV systems and fixed installations, with fixed-wing and rotorcraft applications specifically identified. The supplied product configuration is an off-the-shelf navigation antenna component for integration into a host system.
Installation planning must accommodate a 100×100×23 mm package weighing 225 g, a 12 VDC supply and power consumption below 10 W. Connections comprise one SMA female connector and one J30J 9-pin socket, with a serial data interface. Protection covers GPS L1, GALILEO E1 and BEIDOU B1. The specified interference-source count is three; performance above 95 dB J/S is qualified by typical GPS receiver performance with three broadband interferers from different directions. Operating temperature spans -40 °C to +70 °C.
