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.
