The 1087-071 from Southwest Antennas is a 4 section collinear omni-directional antenna that operates from 1.35 to 1.39 GHz. It provides a peak gain of up to 6 dBi and can handle an input power of up to 50 W. This antenna has an integrated 3.5" flange mount base with lock-wired screw connection to the Type-N(f) RF connector, and a weatherpoof sealed spring that allows the antenna's radome to bend and flex with impact and return to its vertical operating position, helping to reduce risk of damage to the mated RF connector. It is ideal for DOD and military applications.
