AD-27/DB-15-73: Dual-band dual-feed dipole/dipole mobile antenna (100-512 and 700-3000 MHz); 80W

The antenna AD-27/DB-15-73 is a "center-fed" type mobile UHF antenna for the frequency range from 100 - 512 MHz and 700 - 3000 MHz, mainly intended for use in heavy-duty mobile applications. The antenna is designed as a dipole in both  UHF bands and does not require any ground plane, so the electrical performance (GAIN and VSWR) of the antenna is always the same. This specific antenna design allows various types of mounting.
The antenna is composed of a base and radiating element, which is not detachable.
The antenna base is made of aluminum and durable plastic materials. A big stainless steel spring absorbs the shocks and vibrations, and also protects the antenna against impacts. The antenna base has NATO standard four mounting holes equally spaced on a 4.5" (114.3 mm) circle.
The radiating element is made of composite material that enables outstanding strength and roughness even in the hardest conditions of use. The antenna radiating element is painted with black two-component UV-resistant paint. Other colors and connectors are available on request.
