L1 Active GPS Antenna
1575.42 ± 12 MHz
The 21-45-02 antenna is designed to provide operation at the L1 frequency. It is of low profile construction and is supplied in a composite cover with an aluminium alloy baseplate on to which are attached the antenna radiating elements. Within the enclosure is a low noise amplifier (LNA) with a gain of + 33 dB.
The antenna is designed for use on groundplanes of typically 300 mm diameter or more. The antenna operates with nominal Hemispherical coverage in GPS L1 band to allow reception of microwave signals from a number of satellites.
