The L-Band antenna was designed for line of sight voice or data communication circuits. The antenna is vertically polarized and has a frequency range of 1300–1535 MHz with a 100 watt average power capacity. The antenna was specifically designed to optimize maximum radiated power above the horizon by including up-tilt and null fill. Null fill above the horizon ensures the radiated power remains virtually constant allowing for uninterrupted communication between the antenna and the aircraft, while the antenna’s 9 dBi gain accommodates long range communication circuits of over 100 miles. The antenna’s robust design is suitable for extreme environmental conditions.
