AD-18/H-1318 is an omni-directional, vertically polarized VHF dipole antenna for mobile communications in the 130 to 180 MHz range. It is intended for use on vehicles, but can also be affixed to a mast using an optional mounting bracket.
AD-18/H-1318 is a wideband dipole mobile antenna intended for 130 to 180 MHz, mainly intended for use in vehicle applications.
The antenna is composed from two main parts: the radiator and the antenna base.
Electrically the antenna is designed as center-fed thus the electrical characteristics are independent from the ground or mounting place. The radiator is contained in a 43mm diameter fiberglass tube with special elements firmly placed inside, and painted with military green (RAL-6014) two-component UV resistant paint.
The antenna base has an optional built-in active GPS antenna and biconical spring to enable protection against mechanical impacts. Four mounting holes equally spaced on a 4.5" (114.3 mm) circle allows mounting that complies with US/NATO standards.
The antenna can be also be mounted on a mast using the ATP-1827/03 mast mount.
