MHz Bands
DESCRIPTION
Dual-frequency antenna – two bands – one antenna!
Covering both EGSM/NMT-900 and DCS-1800/PCN.
For direct use with:
– an EGSM/DCS-1800/PCN mobile phone (single or dual-band)
or
– an EGSM and a DCS-1800/PCN mobile phone (requires diplexer, type
DIPX 1000/1550).
Stainless steel LX-mount.
Especially suited for roof-mounting.
Provided with FME-connection (supplied without cable).

OPERATION USING A DIPLEXER
In case of operating two transceivers on one antenna at the same time, a
diplexer, type DIPX 1000/1550, is necessary to complete the system. The
tasks of the diplexer are to protect the two receiver inputs from being
destroyed by the transmitter in the contrary band, and to ensure a low-loss
path between the transceiver and the antenna, which is not loaded by the
other branch. For further details please see the separate data sheet on the
DIPX 1000/1550. The diplexer fully covers both bands and, consequently,
tuning to specific frequencies is not required.
COUPLING DIAGRAM
INSTALLATION
The LX-mount is especially suited for roof-mounting. It is recommended to
mount the antenna at the centre of the roof to ensure the best
omnidirectional coverage. Mounting can take place in an 18 mm dia. hole
with access from the outside only. When cleaning the car in car-washing
machines, the whip should be removed – a 9 mm fork spanner can be used.
After wash, the whip is refitted and tightened lightly with the spanner.The
mount is equipped with a bendable section (±15°) to make it possible to
adjust the antenna to an upright position.
