Antenna

The performance of the facsimile receiver is directly related to the antenna installation. In
general, the antenna should be installed as high as possible on the vessel, free from the
influence of nearby antennas, rigging and masts. Be sure to locate the antenna well away
from TX antennas and noise generating equipment. Pay particular attention to the antennas
for MF and HF radio equipment - they can damage the facsimile receiver through induction.
(For better protection against induction, use the preamp unit.)
The FAX-410 can use the following antennas:
• Preamp unit FAX-5 (optional supply) + 2.6 m whip antenna (optional supply)
• Whip antenna (6 m, optional supply)
• Wire antenna (local supply)

3.2.1 General antenna connection

Connect the antenna to the facsimile receiver as shown below.
Connect BK if ship carries MF/HF transmitter, to protect against RF induction. For details
