Marine AntennasCXL 450-3LW-SS

3 dBd Base Station and Marine Antenna for the 450 MHz Band

Description

  • CXL 450-3LW-SS is a 3 dBd, vertically polarised, omnidirectional base station and marine antenna, which covers the UHF band in 4 models with up to 10 MHz overlap.
  • The carefully designed radiating element is sealed in a high-quality, conical glass fibre tube with low wind-load which will ensure performance undisturbed by corrosive environments.
  • Provided with the sturdy “LW-SS” mast mount –  a multipurpose bracket made of stainless steel (AISI 316L).
  • The accompanying U-bolts and fittings are made of stainless steel (AISI 304).
  • 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.
  • 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 450-3LW-SS is a vibration-proof, lightweight, slim-line, corrosion resistant, modern style base station and marine antenna.
