CXL 450-3LW-SS-Ex

ATEX certified, 3 dBd, Omnidirectional Base Station Antenna for the 380 - 470 MHz Band in Hazardous

  • CXL 450-3LW-SS-Ex is a 3 dBd, vertically polarized, omnidirectional base station antenna which covers the 380 - 470 MHz band in four models with up to 10 MHz overlap.
  • The antenna is specified as ATEX antenna for use in zone 2 in potentially explosive areas.

DESCRIPTION

  • Before installing the antenna, read the ATEX Product Manual carefully.
  • The antenna is suitable for use in gas groups IIA, IIB and IIC in zone 2.
  • It’s only necessary to install a ATEX grounding Kit on the LW-SS-Ex bracket, when the point of installation has a different electrical potential than the system.
  • The carefully designed collinear antenna radiating parts elements is made of brass tube and sealed in a high-quality conical glass fibre tube with low wind-load.
  • The accompanying U-bolts and fittings are made of stainless steel.
  • All metal parts in the antenna are DC-grounded. Consequently, the antenna shows a DC-short across the coaxial cable.
