nvistarprofiledrawThe STAR-H NVIStar™ vehicular HF antenna is a low-profile, dual vertical loop system mounted above the roof of a vehicle. Designed for TOC, HMMWV, and other mobile command post applications, it replaces the 16- and 32-foot whip antennas with a dual loop that is only 36 inches tall. It provides line-of-sight HF communications in both NVIS and long range modes.

The standard version offers a single feedpoint for use with HF radios with integrated tuners, such as the AN/VRC-100. A high efficiency version is also available, which includes automatic microprocessor tuning circuitry at the antenna for optimal performance.

The antenna is primarily made from a fiberglass composite for minimum weight and mounts on a standard Army antenna flange mount, such as found on HMMWV communication shelters. With the optional low angle kit, a remote control switch at the operator allows changing between NVIS and longer range communications with ease.
