The Telewave ANT150F2-Omnidirectional Collinear Antenna 148-174MHz, is an extremely rugged collinear antenna. ANT150F2 radiates an omnidirectional propagation pattern with moderate gain and wide vertical beam-width. This compact antenna produces 2.5 dBd gain, and is designed for operation in all environmental conditions. The antenna is constructed with brass and copper elements, with a path to DC ground for lightning impulse protection. All junctions are fully soldered to prevent RF intermodulation. Each antenna is completely protected within a rugged, high tech radome to ensure survival and durability in the worst environments. The “Cool Blue” radome provides maximum protection from corrosive gases, ultraviolet radiation, icing, salt spray, acid rain, and wind blown abrasives.
