AD-18/D-110: wideband mobile VHF monopole antenna, 30 - 110 MHz

The antenna AD-18/D-110 is a wideband VHF vehicle antenna for frequency range from 30 to 110 MHZ, mainly intended for use in heavy duty mobile applications but also as military jammer. The antenna is composed of three main parts: antenna base, lower and upper radiating element. The antenna base is made of aluminum and durable plastic materials. Inside the base is the matching circuitry and (optional) GPS antenna. Stainless steel spring absorbs the shocks and the vibrations, in addition protects the antenna against impacts. Both radiating elements are made of composite materials enable outstanding strength and roughness even in 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.
