INSTALLATION
This antenna should be mounted on the car roof to ensure best
omnidirectional coverage.
Mounting can take place exclusively with access from the outside when
drilling an
18 mm dia. hole. Mounting can take place from the inside by drilling a 14
mm dia. hole. When mounting in a 14 mm dia. hole, remove the bottom
plastic ring of the packing gasket with a sharp cutter.
When cleaning the car in car-washing machines, remove the whip using a
spanner,
size 9 mm. After wash, refit the whip and tighten it lightly with the spanner.

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.
