AD-18/D-3512
The antenna AD-18/D-3512 is an ultra wideband mobile
VHF/UHF antenna for frequency range from 25 to 512 MHZ,
mainly intended for use in heavy duty mobile applications.
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.
