The HT-30 3 to 30 MHz antenna is used for short and medium range skywave propagation circuits. It is designed to handle 14 kW transmitters. The antenna is designed for field operations where transportability is essential and erection and disassembly must be accomplished in a minimum time by a minimum number of personnel. The equipment is stored in transportable two-man carry containers. The antenna consists of two orthogonal broadband dipole elements supported by a 30 ft. telescoping mast at the center of the structure. The elements slope radially outward and toward the ground. Each element is made of five phosphor-bronze wires in a fan shaped configuration that terminate to a resistive load to ground. The telescopic mast is pneumatically operated and is designed for rapid deployment of tactical antennas. It is a PM-456 mast that is modified to provide a 30 foot erection height for the antenna matching unit (AMU). The AMU consists of four identical RF units that match the fan dipole elements to 50 ohms.

The elements are fed using a broadband quadrature hybrid which enables the antenna to radiate either right-hand circular or left-hand circular polarization. The hybrid locate at ground level near the base of the mast. The hybrid outputs connect to the AMU by means of four RG-393 coaxial transmission lines
