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.
