DFA 4/70-Z/...
Dual-frequency Mobile Antenna for the 80 and 450 MHz
Bands
DESCRIPTION
New whip design for optimum wind noise reduction.
This antenna makes it possible to:
- operate 80 and 450 MHz transceivers alternately on the same antenna
- operate two transceivers (80 and 450 MHz) at the same time on one
antenna using a diplexer (type DIPX 225/330 – must 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 Z-mount with ball-joint and wing screw whip-fastening
system.
Simple mounting exclusively with access from the outside.
Models with roof thickness from 2 mm to 7.5 mm mounting from the
inside.
Choice between two connection principles:
Z-mount: FME-connection (supplied without cable).
ZP4-mount: Permanently attached 4 m cable terminated with FME-
connector.
