The antenna AD-4/WB-MHD-4.8 is a wideband mobile HF antenna for frequency range from 1 to 60 MHz, mainly intended for use in heavy-duty mobile applications.
The antenna is composed of five main parts: one antenna base and four radiating elements. The antenna base is made of aluminum and durable plastic materials. Inside the base are the matching circuitry and (optional) GPS antenna. Stainless steel spring absorbs the shocks and the vibrations, in addition protects the antenna against impacts. All radiating elements are made of composite materials that enable outstanding strength and roughness even in the hardest conditions of use.
The antenna base has four mounting holes equally spaced on a 4.5" (114.3 mm) circle which complies with NATO standard. Different base plate dimensions are available on request.
The antenna radiator is painted with military green (RAL-6014) two-component UV resistant paint.
