Marine AntennasCXL 2-3LW

Lightweight, 3 dBd Base Station and Marine Antenna for the 150 MHz Band

Description

  • CXL 2-3LW/… is a 3 dBd, vertically polarised, omnidirectional base station and marine antenna, which covers the VHF-band in 5 models.
  • Provided with the sturdy “LW” mast mount – a lightweight, multipurpose, epoxy-coated mounting bracket made of non-corrosive aluminium.
  • The accompanying U-bolts and fittings are made of stainless steel.
  • To be mounted on vertical or horizontal mast tubes, 16 to 54 mm in outer diameter.
  • 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.
  • 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 carefully designed, broad-banded antenna element is sealed in a high-quality conical glass fibre tube with low wind-load, which will ensure performance undisturbed by corrosive environments.
  • 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.
  • The CXL 2-3LW/… is a vibration-proof, lightweight, slim-line, corrosion resistant, modern style base station and marine antenna.
