The antenna ZD-VUA-25/512M-NF is a wideband mobile VHF/UHF antenna for frequency range from 25 to 512 MHz, mainly intended for use in heavy duty mobile applications.
The fiberglass antenna ZD-VUA-25/512M-NF is a wideband mobile VHF/UHF antenna for frequency range from 25 to 512 MHz, mainly intended for use in heavy duty mobile applications.
The high-gain omnidirectional 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 element 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.
