CXL 70-1/...
Unity Gain Base Station and Marine UHF Antenna
DESCRIPTION
This rod-type UHF antenna is developed for use onboard ships as well as
on masts and covers the 450 MHz band in three models.
The 1” revolving nut mounting system makes it possible to mount the
antenna in the mast, in the auxiliary mast or on the cross-beam. By
means of Procom’s flange mount type “FLG”, it can easily be mounted
even on the rooftop.
This antenna type can be used for a wide variety of purposes. It is very
popular and widely used in connection with 70 cm CELLULAR systems –
as for instance the Nordic Mobile Telephone system NMT – making it
possible to extend the – normally land based – CELLULAR telephone
system for maritime mobile service as well.
The antenna is a ½ λ design and this means that it needs neither
loading coils, groundplane, radials nor other auxiliary arrangements.
Bear in mind that 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. Free mounting
and as high as possible is most preferable, otherwise the SWR and the
radiation diagram will be influenced.
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.
