Procom DFA 450-900-x-... - Manual

DFA 450/900-X/...
450 MHz / 900 MHz Dual-frequency Mobile Antenna
DESCRIPTION
This antenna makes it possible to:
-operate 450 MHz and 900 MHz transceivers alternately on the same
antenna
-operate two transceivers (450 and 900 MHz) at the same time on one
antenna using a diplexer (type DIPX 500/800 – to be ordered
separately)
-operate a dual-frequency transceiver (450 and 900 MHz) on one
antenna (diplexer not required).
Ready-tuned and unity gain on both bands.
Stainless steel X-mount with M6-thread whip-fastening system.
Simple mounting exclusively with access from the outside.
Models available with X-mount (oblong), CX-mount (circular) and MM-
mount (magnetic).
Choice between two connection principles: X-mount, MM-mount: FME-
connection (supplied without cable).
XP4-mount: Permanently attached 4 m cable terminated with FME-
connector.

MOUNTING 18 mm dia. hole
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.
The MiniMag (abbreviated: MM) is a small, light-weight magnetic mount with
a high attaching effect. A silicone layer applied to the contact surface
protects the car roof and ensures maximum friction.
