This military HMMWV is outfitted with Southwest Research Institute’s AVM-375 low-profile antenna set, which consists of four specially designed antenna arrays distributed around the body of the vehicle to reduce the system’s visible signature. The antenna set, shown in lighter-colored packaging, improves mission stealth and vehicle mobility while providing geolocation of enemy forces from a single moving platform.
