AD-27/V190-3108
The antenna AD-27/V190-3108 is a family of wideband
monopole VHF low profile mobile antennas for frequency
range from 30 to 108 MHZ. The antenna has a very low
profile of radiating elements, very low visibility and
very low weight, making it universal and suitable for
installations in heavy trucked as well as lighter wheeled
military vehicles.
The antenna is composed of two main parts: antenna base
and radiating element. The antenna base is made of aluminum
and durable plastic materials. Inside the base is the
matching circuitry for the VHF radiator and (optional)
GPS antenna. Stainless steel spring absorbs the shocks
and the vibrations, in addition protects the antenna
against impacts, while the (optional) tilting mechanism
enables to adjust the inclination radius of the antenna,
when “on move”, or if decided so. Radiating element
is made of conical Stainless Steel rod enabling outstanding
strength and flexibility in the most severe environmental
conditions.
The antenna base has four mounting holes equally spaced
on a 4.5" (114.3 mm) circle which complies with
NATO and US army standard (AS-1729). Different base
plate dimensions are available on request.
