CXL 70-3LW/...

Lightweight, Medium Duty, 3 dBd Base Station and Marine Antenna for the 450 MHz Band

  • CXL 70-3LW/… 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 antenna meets the demand for a medium duty, cost-effective antenna to be chosen, when the exceptional mechanical capabilities of our extremely rugged heavy-duty model CXL 70-3C/… are not needed.

DESCRIPTION

  • 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” 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 SWR 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 70-3LW/… is a vibration-proof, lightweight, slim-line, corrosion resistant, modern style base station and marine antenna.
