RF-1980-AT001

® assuredcommunications™ RF-1980F-AT001 / RF-1980-AT001 TILT-WHIP ADAPTERS for use with a vehicular whip to allow for NVIS communication The RF-1980 family provides whip antennas the flexibility to tilt from 0˚ (vertical) to 50˚, 70˚, and 90˚. The use of a tilt-whip adapter provides radiation patterns that accommodate near vertical incidence skywave (NVIS) propagation. The RF-1980F is a tilt-whip adapter with a spring base that bolts to standard 4.5-inch bolt hole pattern. The length of whip antenna is limited to 16 feet. The RF-1980 is a tilt-whip adapter that mounts directly on a standard whip base. If a locking base is used, a 32-foot whip can be installed with this tilt-whip adapter. Specifications for the RF-1980 Electrical I Frequency Range 2 to 30 MHz I RF Power Capacity 1 kW I Input Impedance 50 ohm, nominal I Radiation Pattern Azimuth - omnidirectional Elevation - see below I Polarization Turns vertically polarized whip into horizontal polarized tilt whip I Gain with 32 foot whip: 0 dBi @ 8 MHz With 16 foot whip: -2 dBi @ 8 MHz Mechanical I Deployed Dimensions RF-1980F 20.5 inch RF-1980 19 inch I Color RF1980F-AT001: CARC green RF-1980F-AT002: CARC tan RF-1980: Flat black I Weight 10 lb (4.5 kg) I Mounting Interface RF-1980F: 4-3/8 inch hole equally spaced on 4.5-inch diameter RF-1980: threads on standard whip base I Installation Time RF-1980F: 10 minutes, 1 person RF-1980: 2 minutes, 1 person Options Environmental I Designed to meet MIL-STD-810 I SB-V16/32: 16- or 32-foot whip (The RF-1980 family are adapters.
