AD-23/35-4-M: Mobile collinear dipole antenna for 820 - 940 MHz, 8.15 dBi

The antenna AD-23/35-4-M is a mobile collinear dipole for use on UHF frequency range from 820 to 940 MHz, mainly intended for use in heavy duty mobile applications. The antenna is composed from two main parts: the antenna base and the radiator. The antenna base has built-in biconical spring enables resistivity against mechanical impacts. Electrically the antenna is designed as collinear dipole thus the electrical characteristics are independent from the ground or mounting place. The antenna base has an option of additional built-in GPS active antenna. Stainless steel spring absorbs the shocks and the vibrations, in addition it protects the antenna against impacts. The radiating elements are enclosed in a tube made of composite material enabling excellent mechanical and atmospheric resistance. The antenna base has four mounting holes equally spaced on a 4.5" (114.3 mm) circle which complies with NATO standard. The antenna radiator is painted with military green (RAL-6014) two-component UV resistant paint.
