Omni AntennasG-CXL 225-450C

Unity Gain, Broad-Banded Base Station Antenna for 225 - 450 MHz. Designed for defense units.


  • G-CXL 225-450C is a 0 dBd gain, omnidirectional base station antenna.
  • The antenna is extremely broad-banded and covers the complete band 225 - 450 MHz.
  • G-CXL 225-450C is designed for fixation on supporting tubes with outer diameter between 27 mm and 65 mm.
  • The construction of the mount makes it possible to lead the cable either inside or along the outside of the mast tube.
  • A glass fibre tube completely encloses the carefully designed radiating element to ensure long dependable service in all climates.
  • Atmospherical discharges are immediately led to ground as all metal parts are DC-grounded (consequently, the antenna shows a DC-short across the coaxial cable).
  • This antenna is used where reliability is of utmost importance. A long lifetime has been taken into consideration when designing this antenna – it is sturdy and strong.
