CXL 70-3/GPS 4/...
Dual Band Antenna for the UHF Band and GPS
DESCRIPTION
This active antenna has been designed for use on the TETRA band and
GPS.
The antenna consists of a high-performance 3 dBd 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 colinear antenna for the UHF band frequency
range within 380 - 430 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 CXL 70-3/GPS 4/... is designed to
withstand the roughest of climate conditions, ensuring many years of
trouble-free service.
