This active antenna has been designed for use by the Universal Shipborne Automatic Identification System (AIS) on all waterways.
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 maritime VHF frequency range 156 – 162.5 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 AIS 2/GPS 4 is designed to withstand the roughest of climate conditions, ensuring many years of trouble-free service.
