Each member of the series is comprised of base mounted, broadband dipole units mounted colinearly within a sealed epoxy fiberglass housing. Size depends upon the number of signal channels desired. The minimum configuration is only 66 inches tall and provides two UHF channels. The maximum configuration is 220 inches tall and provides six independent channels.
Each radiator is broadband and covers the entire 225 – 400 MHz band without tuning. Each channel has a separate input and handles RF powers to 50 watts with a VSWR, on 50 ohms, of less than 2.0:1. Pattern coverage is omnidirectional with maximum signal intensity along the horizon. The minimum isolation between channels is 30 dB. Because of the inherent broadband characteristics and balanced electrical design, the CA-1140 Series antennas are insensitive to mounting location and surrounding environment.
CA-1140 Series antennas are designed to meet MIL-STD-167, Type I Vibration and the Service Conditions of MIL-STD-810B.
