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.
