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.

When ordering, the operating frequencies in both bands must be stated. In

case of duplex operation please specify TX and RX frequencies. In case of

application for CELLULAR systems please state names of CELLULAR

networks.

All whips are compatible with all mounts.

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.
