Laird Technologies – FG4503 – 450-460MHz 3dB Fiberglass Omni Antenna. Connectivity”s FG Series omnidirectional base station antennas incorporates a collinear design that is enclosed in high density fiberglass, which is covered with a protective ultraviolet inhibiting coating. The radiating elements are carefully phased to provide maximum gain in the horizontal plane. The mounting sleeves are tuned to eliminate RF currents from the transmission line, resulting in a “cold” sleeve that allows for greater freedom in mounting. The antenna’s high quality and well-focused beam provides the best efficiency with highest gain. Maximum Rated Wind Velocity 125 mile/h. Type of Jumper Included Not Specified. Item Length 44 in.
