Aircraft antenna 20-2041

GPS

The 20-2041 active GPS antenna operates in the GPS L1 and L2 bands. The antenna is certified to military and civil operational performance standards, including WAAS operation. The antenna operates with hemispherical coverage with Right Hand Circular Polarisation (RHCP) reception, excellent symmetry and cross‐polar performance. The low noise Antenna Electronics (AE) amplifies signals in the two GPS bands (separately for maximum performance), while rejecting out‐of‐band signals. The AE also incorporates a limiter circuit protection from high power in‐band signals. Power is applied to the AE on the centre conductor of the RF connector. The minimum AE gain is 26.5 dB. The antenna element and AE are housed within a high performance shell which is sealed to an aluminium enclosure/baseplate. The shell provides protection against rain, ice, fluid contamination and lightning.
