Procom DFA 450-900-zg-... - Manual

DFA 450/900-ZG/..
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 ZG-mount with M8-thread whip-fastening system.
Simple mounting exclusively with access from the outside.
Choice between two connection principles: ZG-mount : FME-connection
(supplied without cable).
ZGP4-mount : Permanently attached 4 m cable terminated with FME-
connector.

INSTALLATION
The ZG-mount is designed for mounting in a 21 mm dia. hole on horizontal
surfaces as e.g. roof top or trunk lid, with access from the outside only.
A good contact surface on the inside of the car body must always be
ensured, thus enabling the base plate to get in direct contact with the metal
parts of the car, which is of utmost importance for proper performance of
the antenna.
The ZG-mount is provided with an M8 x 1 thread mount system. This
construction meets the demand for a low profile mobile mount with a slim
appearance and with protection against theft of the antenna whip.
When cleaning the car in car-washing machines, the whip is easily removed
using a fork spanner. The whip is refitted again by screwing it onto the
thread stud and tightening it with the spanner.
