    Accessory: High/Low UHF Satcom Mount

    The ACC-0381 High/Low Angle UHF Satcom Mount is used in conjunction with either X-Wing Antenna UC-3004-381 or Tacsat Antenna UC-3004-481 as an accessory, to increase the antenna's gain passively for satellite circuits by 3 dB (doubles the antenna gain). It also has a built-in secondary antenna to enable Line Of Sight/LOS communications, or to operate through low angle or near horizon satellites. The ACC-0381 must be mounted on a metal surface, such as the chassis of a vehicle or a ground plane. This provides the main antenna (UC-3004-381R or UC-3004-481R) the optimum height for satellite operation (High Angle circuit). It also provides the Mount's internal antenna a counterpoise against which to operate for Low elevation Angle communications circuits (Line of Sight, airborne and near horizon satellites).

    The Low Angle radiating element contained within the ACC-0381 Mount is marked with an engraved "L". This element requires a ground plane to operate normally, and to provide the stated gain figures. The Low Angle element is usually used for ground-ground or ground-air communications. This element can also be used effectively with satellites residing a low elevation angles (near the horizon), where an X-Wing antenna would have lower efficacy.

    The ACC-0381 mount is compatible with 13 cm (5") x 8 cm (3") X-Wing Direct Bolt Mount
