Marine AntennasCXL 70-5C/T-7/...

Colinear, 5 dBd Base Station Antenna and Marine Antenna with 7 degrees electrical downtilt


  • CXL 70-5C/T-7/... is a 5 dBd, vertically polarized, omnidirectional base station and marine antenna, covering the 380 - 470 MHz band.
  • The antenna is provided with our “C” universal fixation bracket made of epoxy-coated, seawater-resistant aluminium. The accompanying U-bolts and fittings are made of stainless steel.
  • CXL 70-5C/T-7/... can be mounted on 27 to 65 mm dia. mast tubes and it is possible to lead the cable either along the inside or on the outside of the mast tube.
  • The carefully designed radiating element is sealed in a high-quality, conical glass fibre tube with low wind-load, ensuring a 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 exceptional mechanical capabilities of this antenna ensure long dependable service in all environments.
