CXL 2-1/...

Base Station and Marine VHF Antenna

DESCRIPTION

  • This base station and maritime VHF antenna 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 auxilliary mast as well as on the cross-beam. By means of Procom’s flange mount it can also be mounted on deck or rooftop.
  • 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 mast, 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 ½ λ design and this means that it needs neither loading coils, ground-plane, radials nor other auxiliary arrangements.
  • CXL 2-1/... can, without problems, operate with duplex radioes and on the semi-duplex channels, owing to the fact that it is broad-banded (see SWR diagram). In other words, CXL 2-1/... has a shipshape SWR on the RX-frequencies, which is just as important as it is for the TX-frequencies.
  • Furthermore, 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.
