CXL 3-3C
Sturdy 3 dBd Gain Base Station Antenna for the air Band
DESCRIPTION
CXL 3-3C is a sturdy, 3 dBd, vertically polarized, omnidirectional base
station antenna, which covers the air band.
The antenna is provided with our “C” mast bracket, which is a universal,
epoxy-coated mounting bracket made of non-corrosive aluminium. The
accompanying U-bolts and fittings are made of stainless steel.
The antenna can be mounted on 27 to 65 mm dia. mast tubes and it is
possible to lead the cable either along the inside or on the outside of the
mast tube.
The phasing of the radiating elements is carefully adjusted to yield
maximum gain in the horizontal plane, with the level of the sidelobes
reduced to a minimum. Special emphasis has been laid on obtaining a
large bandwidth both in relation to SWR and gain.
The broad-banded antenna element is completely enclosed in a glass
fibre shroud, which will ensure performance undisturbed by corrosive
environments.
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.
This antenna is constructed to ensure long dependable service in all
climates.
