Antenna 30829

The 30829 rod antenna is a quarter-wave, duplex vehicle antenna. It is designed to work with vehicle radiotelephones operating in every mode (particularly in duplex or simiduplex mode with duplex spacing of 9,8 MHz) in operating band  80 MHz, i.e. in frequency ranges: 74,10 ÷ 74,80 MHz and 83,90 ÷ 84,60 MHz.

This type of antenna is adapted for installation on any motor vehicle. The place of mounting of the antenna needs to be close to the center of a vehicle's metal bodywork. It is posiible to install the antenna in the centre of TAXI lamp LZ type with 30820-1000/1 connectors set, which can be ordered additionaly.

Operating conditions:

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. It is posiible to install the antenna in the centre of TAXI lamp LZ type with 30820-1000/1 connectors set. 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.
