COMROD MODULAR ANTENNAS
8m, 7m, 6m, HF Transmitting,MF-HF Receiving Antennas
High quality and high performance fiberglass rod antennas
Transmitting antennas for simplex and duplex SSB
Receiving antennas for MF-HF and SSB
Application:
The modular system is our answer to the GMDSS.
The antennas can be part of any MF/HF communication
system but is specially designed to satisfy the demands
of the GMDSS.
Depending on the equipment and the traffic pattern of
the vessel you can choose between antennas of
6, 7 or 8 m length.
Different installations demand different mounting
possibilities. The modular system provides you with all
the solutions you need:
* Installation in mast or post or directly to wall.
* Installation on welded brackets.
* Flange or deck mounting with side feed.
* Flange or deck mounting with end feed.
The flange mounted, side feed versions can be fitted
with a manual or electrical tilting device.
The antennas can be equipped with connecting kit for
transmitting/transceivers (AT-Kit) or a kit for receiving
(AR-Kit). The receiving kit can be with matching
transformer (AR/T-Kit).
Receiving antennas can be supplied with protection
against static discharges that can harm the receiver,
contact Comrod for prices and delivery time.
