MODEL 3115

The Model 3115 from ETS-Lindgren is a Double-Ridged Guide Horn Antenna that operates from 750 MHz to 18 GHz. It is designed for automated EMC testing and field strength measurements, providing continuous frequency coverage across the band. This 50-ohm linearly-polarized antenna has a directional radiation pattern and provides uniform gain with no performance degradation from higher-order modes. It can handle a continuous input power of 300 W and a peak input power of 500 W with a VSWR of up to 5.0:1.

The Model 3115 is constructed from powder-coated aluminium and is available in a housing measuring 24.4 × 20.6 × 15.9 cm and has an N-type (female) connector. It is individually calibrated at 1 m in accordance with SAE ARP 958 and supports standard tripod mounting with a 1/4"-20 threaded interface.
