Omni Bifilar Antenna, LHCP, 2.35 - 2.52 GHz, 4.3 dBic, Integrated Sealed Spring, Internal Bandpass Filter
Product Overview
Southwest Antennas Part# 1032-045 is an Omni-directional, bifilar antenna with an operation frequency of 2.35 - 2.52 GHz and 4.3 dBic of peak gain. The antenna's bifilar design and left-hand circular polarization (LHCP) make it ideal for communication with overhead aircraft or UAVs due to the lack of keyhole null in the antenna's radiation pattern. 1032-045 is a receive-only antenna. This product features an integrated bandpass filter for improved rejection around cell sites and blocking out interference.
1032-045 features an integrated spring base with heat shrink cover, adding flexibility to the antenna while protecting the spring from dust, dirt, mud, rain, and other debris. This antenna also features a rugged, flat black, fiberglass radome and rotating Type-N(m) RF connector.
