CXL 900-3/...

3 dBd Gain, Base Station and Marine 900 MHz Antenna for

Mounting on Threaded 1” Water Pipe

DESCRIPTION

CXL 900-3/… is a 3 dBd, vertically polarized, omnidirectional rod-type

base station and marine antenna which covers the 900 MHz band in

three models.

The 1” revolving nut mounting system is standard throughout the base

station or maritime sector, and several different mounting brackets are

available, making it possible to install the antenna either on the

masthead using FLG or SMR 2, side-mounted on the mast (SMR 1), or

mounted on a cross-beam (FLG). Also, the antenna can be mounted on

deck or rooftop by means of the FLG. (See below).

CXL 900-3/… is especially suitable for use in connection with 900 MHz

CELLULAR systems – making it possible to extend the normally land-

based cellular telephone system for maritime mobile service as well.

The phasing of the radiating elements is adjusted to yield maximum

gain in the horizontal plane, with the level of the sidelobes reduced to a

minimum.

The higher the antenna is mounted, the better coverage. Avoid

mounting the antenna parallel to or in the neighbourhood of other metal

parts, such as masts, supporting wires etc., otherwise the SWR and the

radiation pattern may be strongly influenced.

To substantially reduce noise caused by atmospherical discharges, all

metal parts in the antenna are DC-grounded. Consequently, the antenna

shows a DC-short across the coaxial cable.

A conical glass fibre tube completely encloses the carefully designed

radiating element to ensure long dependable service in all climates.
