Product Overview
Southwest Antennas Part # 1032-047 is an Omni-directional quadrifilar antenna with an operational frequency range of 1.05 - 1.35 GHz, and a maximum gain of 3.1 dBic.
The antenna's quadrifilar architecture provides a number of benefits, including complete overhead radiation pattern cover over the antenna, eliminating the keyhole null that is present with many Omni-directional antennas. The circularly polarized design is ideal for communication with overhead aircraft, UAVs, or for C-UAS product solutions.
An integrated bandpass filter helps to eliminate interference from other co-located radios operating outside of the antenna's operational frequency band, providing increased performance for attached radio systems.
Note: This antenna is for receive-only applications and includes an integrated RF limiter. The limiter has a maximum input power of 1.5W, and it compresses input signals between +5 dBm and +30 dBm down to 0 dBm.
