CXL 4/70C/...
Dual-frequency, Base Station Antenna for the 80 MHz and
TETRA Band
DESCRIPTION
CXL 4/70C/... is a dual-frequency base station antenna - two bands with
only one antenna.
This antenna makes it possible to:
operate 4 m and TETRA transceivers alternately on the same
antenna.
operate two transceivers (4 m and TETRA) at the same time on one
antenna using a diplexer (type DIPX 225/330 - must be ordered
separately).
CXL 4/70C/... is designed for fixation on supporting tubes with outer
diameter between 27 mm and 65 mm.
The construction of the mount makes it possible to lead the cable either
inside or along the outside of the mast tube.
Atmospherical discharges are immediately led to ground as all metal
parts are DC-grounded (consequently, the antenna shows a DC-short
across the coaxial cable).
