MA 70/GPS 4/…
Dual Band Antenna for the UHF band e.g. TETRA, CDMA, ICE, 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 ½ 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.
