Mobile antenna 30832

The 30832 rod antenna is designed to work with vehicle radiotelephones operating in frequency band164 ÷ 174 MHz. The antenna is equipped with a joint, which enables inclination of the antenna radiator to the ground. This type of antenna is adapted for installation on any motor vehicle.

Operating conditions:

The 30832 antenna needs to be mounted to the metal body of a vehicle or to the metal bracket which is galvanically connected to the bodywork, which is a “ground plane” for the antenna. The place of mounting of the antenna needs to be close to the center of the largest horizontal plane of vehicle’s metal bodywork or close to the center of the whole structure of a vehicle. This way of installation ensures correct antenna impedance and a horizontal radiation pattern closest to circular.

The hole of a diameter Φ 16,2 mm between the antenna base (shield of a coaxial cable supplying an antenna) and the body work of a vehicle is required for installation of the antenna.
