CXL 70-8HD/…-PT is an 8 dBd, vertically polarized, omnidirectional base
station antenna for the 450 MHz band.
The antenna has a bandwidth of 20 MHz. Please specify centre
frequency or duplex TX and RX when ordering.
The antenna has been approved to withstand lightning (10/350 μs
impulses/100 kA) according to EN 61643-11, VDE 0855-300 and VDE
0185-305-114 in FH-Kiel Laboratory in Germany.
The antenna is provided with our sturdy type “HD” mast mount, which is
a heavy-duty, multipurpose mounting bracket made of non-corrosive
aluminium. The accompanying U-bolts and fittings are made of stainless
steel.
The antenna can be mounted on mast tubes of 58 to 105 mm in outer
diameter. Further, the construction of the mount makes it possible to
lead the cable either along the inside oron the outside of the mast tube.
In designing this antenna special emphasis has been laid on obtaining a
large bandwidth both in relation to SWR and gain, making this antenna
highly suitable for duplex operation with large spacing between the TX
and RX frequencies. 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.
The antenna element is sealed in a high-quality, conical glass fibre tube
with low wind-load, which will ensure performance undisturbed 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 70-8HD/…-PT is a vibration-proof, slim-line, corrosion-resistant,
modern style base station antenna.
The CXL 70-8HD/... PT can be ordered on other frequencies on request.

PLEASE NOTE
When using the CXL 70-8HD/…-PT at windy locations where wind speeds of
more than (e.g. 150 km/h) can be expected, the antenna must be mounted
on the side of the mast and the top section of the glass fibre tube stabilized
with a bracket. For this purpose the Fixatid Bracket FB-HD/78 with the
slideable side mounting Arms (SMC) can be used.
