G-CXL 70-1LW

Marine AntennasG-CXL 70-1LW

Unity-Gain, Omnidirectional Base Station and Marine Antenna for the 450 MHz Band. Designed for defense units.

Description

  • G-CXL 70-1LW/… is a 0 dBd, vertically polarized, omnidirectional base station and marine antenna which covers the 450 MHz band in three models.
  • The carefully designed, broadbanded ½ λ-dipole radiating element is made of brass tube and sealed in a high-quality conical glass fibre tube with low wind-load.
  • Provided with the sturdy “LW” mast mount – a lightweight, multipurpose, epoxy-coated mounting bracket made of non-corrosive aluminium.
  • The cable can be led either on the outside or along the inside of the mast tube.
  • Large bandwidth with respect to both VSWR and gain.
  • 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.
