Unity-Gain, Omnidirectional Base Station and Marine Antenna for the 450 MHz Band
DESCRIPTION
CXL 70-1LW/… is a 0 dBd, vertically polarized, omnidirectional base station and
marine antenna which covers the 450 MHz band in three models.
The carefully designed, broadbanded ½ λ-dipole radiating element is made of
brass tube and sealed in a high-quality conical glass fibre tube with low wind-
load.
Provided with the sturdy “LW” mast mount – a lightweight, multipurpose, epoxy-
coated mounting bracket made of non-corrosive aluminium.
The accompanying U-bolts and fittings are made of stainless steel.
To be mounted on vertical or horizontal mast tubes, 16 to 54 mm in outer
diameter.
The cable can be led either on the outside or along the inside of the mast tube.
Large bandwidth with respect to both VSWR and gain.
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 CXL 70-1LW/… is a vibration-proof, lightweight, slim-line, corrosion resistant,
modern style base station and marine antenna.
