DFA 2/900-X/...
Dual-frequency Mobile Antenna for the 160 and 900 MHz
Bands
DESCRIPTION
New whip design for optimum wind noise reduction.
This antenna makes it possible to:
- operate 160 MHz and 900 MHz transceivers alternately on the same
antenna.
- operate two transceivers (160 and 900 MHz) at the same time on one
antenna using a diplexer (type DIPX 225/330 – to be ordered
separately).
- operate a dual-frequency transceiver (160 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) 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.
