MA 70/GPS 4/...

Dual Band Antenna for the UHF Band and GPS

DESCRIPTION

This active antenna has been designed for use on the UHF band e.g.

TETRA, CDMA, ICE, and GPS.
The antenna consists of a high-performance glass fibre- encapsulated

antenna element and an active GPS antenna.

The latter is built into the bottom part of the antenna together with a

diplex filter. Only one down lead cable is therefore necessary.
The antenna element is a 1/2 λ antenna for the UHF band frequency

range within 380 - 467 MHz.
The GPS antenna has a full hemispherical coverage and a built-in high-

gain, low-noise amplifier.
The necessary supply voltage (5 V DC) for the amplifier is delivered

through the down lead coaxial cable. Up to 30 m of

RG 214/U coaxial cable can be used between the antenna and

the receiver/transceiver.
By careful choice of materials, the MA 70/GPS 4/... is designed to

withstand the roughest of climate conditions, ensuring many years of

trouble-free service.
