2.7 dBd Gain, Base Station and Marine 900 MHz Antenna for Mounting on Threaded 1” Water Pipe

Description

  • CXL 900-3 is a 2.7 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. (See accessories).
  • CXL 900-3 is especially suitable for use in connection with 900 MHz CELLULAR systems – making it possible to extend the normally land-based cellular telephone system for maritime mobile service as well.
  • The phasing of the radiating elements is adjusted to yield maximum gain in the horizontal plane, with the level of the sidelobes reduced to a minimum.
  • The higher the antenna is mounted, the better coverage. Avoid mounting the antenna parallel to or in the neighbourhood of other metal parts, such as masts, supporting wires etc., otherwise the VSWR 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.
