CXL 3-1LW
Unity-Gain, Omnidirectional Base Station Antenna for the International Aircraft Band
Description
- CXL 3-1LW is a 0 dBd, vertically polarized, omnidirectional base station antenna for the 118 – 137 MHz civil aircraft band.
- The antenna is a broad-banded ½ λ dipole design, and it is equipped with our type “LW” mast mount, which is a lightweight, multi-purpose, epoxy-coated aluminium mounting bracket with stainless steel fittings.
- The antenna can be mounted on vertical or horizontal mast tubes, 16 to 54 mm in outer diameter. Further, the construction of the mount makes it possible to lead the cable either along the inside or on the outside of the mast tube.
- 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.
- 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.
- CXL 3-1LW is a vibration-proof, lightweight, slim-line, corrosion-resistant, modern style base station antenna.
