CXL 900-1/...

Unity Gain Base Station and Marine 900 MHz Antenna for

Mounting on Threaded 1” Water pipe

DESCRIPTION

The CXL 900-1/… is a 0 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.

CXL 900-1/… is especially suitable for use in connection with 900 MHz

CELLULAR systems – as for instance the Nordic Mobile Telephone

system NMT 900 – making it possible to extend the normally land-based

cellular telephone system for maritime mobile service as well.

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

mounting the antenna parallel with 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.
