CXL 70-3LW/...

Lightweight, Medium Duty, 3 dBd Base Station and

Marine Antenna for the 450 MHz Band
DESCRIPTION
CXL 70-3LW/… is a 3 dBd, vertically polarised, omnidirectional base station and marine
antenna, which covers the UHF band in 4 models with up to 10 MHz overlap.
The antenna meets the demand for a medium duty, cost-effective antenna to be
chosen, when the exceptional mechanical capabilities of our extremely rugged heavy-
duty model CXL 70-3C/… are not needed.
The carefully designed radiating element is sealed in a high-quality, conical glass fibre
tube with low wind-load, which will ensure performance undisturbed by corrosive
environments.
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 SWR and gain. SPECIFICATIONS
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 Electrical
coaxial cable. Model CXL 70-3LW/...
The CXL 70-3LW/… is a vibration-proof, lightweight, slim-line, corrosion resistant,
30 MHz wide frequency segments within 380 - 470 MHz. See model
modern style base station and marine antenna. Frequency
