AD-18/G-50300: Wideband UHF Mobile Dipole Antenna; 500 - 3000 MHz; 500 - 200 W CW; 1 - 2.5 dBi; N female

The antenna AD-18/G-50300 is a wideband UHF dipole ("center-fed") antenna for frequency range from 500 to 3000 MHz, mainly intended for use in heavy duty mobile applications. The antenna is composed of two main parts: the antenna base and the radiating element. The antenna base is made of aluminum and durable plastic materials. Inside the base is mounted (optional) GPS antenna. Stainless steel spring absorbs shocks and vibrations. Radiating elements are made of aluminium alloy and are enclosed inside epoxi composite tube 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 black PU two-component UV resistant paint.
