Laird Technologies – FG4505 – 450-460MHz 5dB 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. Qty/ Uom 1 Each. Lightning Protection DC Ground. Gain dBd 5 dBd. Maximum VSWR 2.0:1.
