AD-27/DB-3512

AD-27/DB-3512

The antenna AD-27/DB-3512 is dualband monopole/dipole mobile antenna intended for use in heavy-duty mobile applications. The antenna is covering frequency range from 30 to 108 MHz and from 225 to 512 MHz. 
Due to the special monopole design in the radiator, the ground for the VHF is not needed. That way the antenna can be also installed on a mast.
The antenna is composed of two main parts: antenna base and radiating element. The antenna base is made of aluminum and durable plastic materials. Stainless steel spring absorbs the shocks and the vibrations, in addition, protects the antenna against impacts. The antenna base has build-in surge protection. The radiating element is made of composite materials that enable outstanding strength and roughness even in the 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. The antenna radiator is painted with military green (RAL-6014) two-component UV resistant paint. Other colors are available on request.
