Procom DFA 4-70-z-... - Manual (Page 2)

INSTALLATION
This antenna is supplied with type Z-mount. The whip is fastened to the
mount by means of our standard ball-joint and wing screw system. The
adjustable ball-joint ensures that the whip can always be mounted in a
vertical position independent of the angle of the installation spot.
The Z-mount is particularly well suited for mounting on car-roofs because of
its ability to be installed exclusively with access from the outside. The Z-
Mount for roof thickness from 2 mm to 7.5 mm must be mounted from the
inside. However, the antenna can be installed anywhere on the car, as the
Z-mount is equally well suited for mounting on e.g. trunk or wing.

Do not use sealer on rubber gasket or other places.
3. OPERATION USING A DIPLEXER
Several advantages are gained by using only one antenna. Only one single
hole has to be drilled into the car body, only one cable installation has to be
run, the car appearance is not destroyed by carrying several whips and also,
it may be a particular demand that it should not be too obvious to see that
the car is equipped with transceiving equipment.
In case of operating two transceivers on one antenna at the same time, a
diplexer, type DIPX 225/330 is necessary to complete the system. (See the
coupling diagram below). 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 225/330.
The diplexer fully covers both bands and, consequently, tuning to specific
frequencies is not required.
COUPLING DIAGRAM
PLEASE NOTE
As standard the antenna is provided with wing screw. However, the wing
screw may be replaced by the less obtrusive hat screw (with key), which
also gives an improved protection against theft. To order the antenna with
hat screw, please add a "K" to the antenna designation.
