VHF Antenna
The antenna requirements
Any good quality antenna meeting the requirements shown below
may be used. A high-gain antenna is preferable.
• Frequency range: 155 to 164 MHz
• Impedance: 50 ohms
• Polarization: Vertical
• Handling power: 30 W/ min
• Quality: Able to withstand marine environment
Mounting considerations
• The antenna should be well separated from nearby antennas, masts,
and other interfering objects.
• The higher the antenna is mounted above the horizon, the further
the communications range.
Mounting procedure
The basic mounting procedure for antennas supplied by FURUNO is
as follows, however consult appropriate outline drawing for details.
1. Fasten the antenna bracket to the stanchion.
2. Set the antenna to the antenna bracket and tighten bolts.
3. Screw the coaxial cable plug into the antenna.
CH70 Rx Antenna
The antenna should be well separated from nearby antennas, masts,
and other interfering objects.
The mounting procedure is the same as that for the VHF antenna,
however consult appropriate outline drawing for details.
Handset Hanger
The handset hanger can be mounted at the front or rear of the trans-
ceiver unit. To mount the hanger at the rear of the unit, a connector
and connector assembly are required (option). The mounting loca-
tion should provide easy access to front panel controls while operat-
ing the handset. Also, the length of the standard handset cable is 50
cm, so locate the handset hanger within 50 cm of the unit. (Longer
cables are available optionally.)
