CXL 70-3/...
3 dBd Gain Base Station and Marine UHF Antenna
DESCRIPTION
This collinear UHF antenna with 3 dBd gain 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 auxiliary mast as
well as on the cross-beam. By means of Procom’s flange mount type
“FLG”, it can also be mounted on deck or rooftop.
The CXL 70-3/… is in widespread use in connection with
450 MHz CELLULAR systems. The antenna makes it possible to extend
the – normally land based – CELLULAR telephone system service for
maritime use as well, and here the 3 dBd gain of the antenna comes to
definite advantage.
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 masts, 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 needs neither loading coils, ground-plane, radials nor other
auxiliary arrangements.
The antenna is a grounded radiator antenna and therefore it shows a
DC-short across the coaxial cable.
A conical glass fibre tube completely encloses the carefully designed
radiating element to assure long dependable service in all climates.
