CXL 130-1-Ex

ATEX certified, 0 dBd, Omnidirectional Base Station Antenna for the International Aircraft Band in H

  • CXL 130-1-Ex is a 0 dBd, vertically polarized, omnidirectional base station antenna for the 118 - 137 MHz civil aircraft band.
  • 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.
  • The antenna is a broad-banded ½ λ dipole design.
  • The antenna can be mounted on threaded 1" water pipe using the supplied 1" revolving nut. In this way, a nice, slim installation is obtained.
  • A wide variety of accessory mounting hardware (see below) gives ample choice regarding alternative ways of installation.
  • All metal parts in the antenna are DC-grounded. Consequently, the antenna shows a DC-short across the coaxial cable.
  • A conical glass fibre tube with very low wind-loading completely encloses the carefully designed radiating element to ensure long dependable service in all climates.
