DFA 2/70-X/...

Dual-frequency Mobile Antenna for the 160 and 450 MHz

Bands

DESCRIPTION

New whip design for optimum wind noise reduction.

This antenna makes it possible to:

– operate 160 MHz and 450 MHz transceivers alternately on the same

antenna

– operate two transceivers (160 and 450 MHz) at the same time on one

antenna using a diplexer (type DIPX 225/330 – to be ordered

separately).

Only a single hole has to be drilled instead of two.

Car appearance is not destroyed by an “antenna farm”.

Ideal for covert services.

Stainless steel X-mount with M6-thread whip-fastening system.

Simple mounting exclusively with access from the outside.

Models available with X-mount (oblong) and CX-mount (circular).

Choice between two connection principles:

X-mount: FME-connection (supplied without cable).

XP4-mount: Permanently attached 4 m cable terminated with FME-

connector.

ORDERING DESIGNATIONS

TYPE PRODUCT NO. MOUNT VERSION

DFA 2/70-X/... 130000688 X-mount with FME-system

DFA 2/70-XP4/... 130000684 XP4-mount with 4 m cable

and FME-connector

The antenna is delivered factory-tuned to two single frequencies, one

frequency in each band. These two frequencies (stated in MHz) must be

specified when ordering as can be seen from the ordering designations. In

case of duplex operation, only the TX frequency should be stated.
