The AS-177B/UPX Antenna is designed for omni-directional or land-based IFF/SIF installation. The radiating element consists of a full-wave center feed dipole with a conical skirt to prevent currents from flowing on the supporting mast. The antenna is enclosed in fiberglass radome which protects the high voltage points from moisture, dirt, or physical contact. The antenna is mounted directly to a 1-1/2" pipe and clamped by two (2) 5/16" bolts to prevent it from turning on the mounting pipe. The antenna is manufactured and qualified to Military Specification MIL-A-28745.
