CXL 2-1/... Marine and Base Station VHF/AIS Antenna, 160 MHz Band
This maritime and base station VHF antenna is developed for use on board ships as well as on masts and thanks to the 1” revolving nut mounting system it can be mounted in the mast, in the auxilliary mast as well as on the cross-beam. By means of PROCOM’s flange mount it can also be mounted on deck or rooftop.
Bear in mind that the higher the antenna is mounted the better coverage. Avoid mounting the antenna parallel with and in the neighbourhood of other metal parts, such as mast, supporting wires etc. Free mounting and as high as possible is most preferable, otherwise the SWR and the radiation diagram will be influenced.
The antenna is a 1/2λ design and this means that it needs neither loading coils, ground-plane, radials nor other auxiliary arrangements.
CXL 2-1/... can, without problems, operate with duplex radios and on the semi-duplex channels, owing to the fact that it is broad-banded (see SWR diagram). In other words, CXL 2-1/... has a shipshape SWR on the RX-frequencies, which is just as important as it is for the TX-frequencies.
Furthermore, the antenna is a grounded radiator antenna and therefore it shows a DC-short across the coaxial cable.
A conical glassfiber tube completely encloses the carefully designed radiating element to assure long dependable service in all climates.

Built-in high gain, low noise amplifier.
Input filter for thorough RF-overload protection.
Right-hand circular polarisation (RHCP).
High rejection of cross-polarised reflections prevents fading caused by multipath propagation.
5 V supply voltage (3 V respectively 12 V available on request).
DC supply via RF-connector.
EMC tested to IEC 801 and IEC 255.
Total design carried out to make the antenna withstand tough environments.
Comprehensive range of accessory mounting brackets available.

AIS 2/GPS Dual Band Antenna for the UAIS (AIS) Standard
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 glassfiber antenna element (based on CXL 2-1, the very wellknown antenna in the maritime sector), an active GPS-antenna, which is built into the antenna mount and a low-loss filter. Then only one downlead cable is necessary.
The antenna element is a 1/2λ antenna for the maritime VHF frequency range 150-170 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 downlead coaxial cable. Up to 30 m of RG 214/U coaxial cable can be used between the antenna and the receiver/transceiver.
The earthing wire ensures static discharging to ground, and thereby also prevents noise pick-up from the ship’s installations running on the outside of the coaxial cable.
By careful choice of materials, the AIS 2/GPS is designed to withstand the roughest of climate conditions, ensuring many years of trouble-free service.

AIS 2/GPS-DM Deck-mounting Dual Band Antenna for the UAIS (AIS)
 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 glassfiber antenna element (based on CXL 2-1, the very wellknown antenna in the maritime sector), an active GPS-antenna, which is built into the antenna mount and a low-loss filter. Then only one downlead cable is necessary.
The antenna element is a 1/2λ antenna for the maritime VHF frequency range 150-170 MHz.
The GPS-antenna has a full hemispherical coverage, and a built-in high gain, low noise amplifier. The accompanying tapered spacer is used to compensate for inclining surfaces to make the antenna stand in a vertical position. The disc is made of UV-stabilized plastic and is able to level out deck-tilting up to 7.5°.
The necessary supply voltage (5 V DC) for the amplifier is delivered through the downlead coaxial cable. Up to 30 m of RG 214/U coaxial cable can be used between the antenna and the receiver/transceiver.
The earthing wire ensures static discharging to ground, and thereby also prevents noise pick-up from the ship’s installations running on the outside of the coaxial cable.
