Antenna Selection And Installation - Uniden UM455 Owner's Manual

Regulations and Safety Warnings
The minimum qualification to operate a VHF radio with or without DSC is a Marine
Radio Operator's VHF Certificate of Proficiency (MROVCP). VHF radios are covered
by a Class License so an individual station license is no longer required.
The Marine Radio Operator's Handbook produced by the Australian Maritime College
provides further information about qualifications, licensing and DSC operations. It is
available at www.amcom.amc.edu.au

Antenna Selection and Installation

Your UM455 has been designed to accommodate all of the popular marine VHF
antennas. However, the selection and the proper installation of the antenna is the
responsibility of the user or installer.
The antenna used with this radio should be installed using the following guidelines to
ensure a safe distance between the antenna and persons close by.
• Small whip antennas (3 dB) or smaller should be installed with at least 1m away
from any area where people are likely to be.
• Larger antennas (6 dB or 9 dB) should be installed with at least 2m away.
• While the radio is transmitting, do not come closer to the antenna than the
recommended safe distance.
• Do not touch the antenna when the radio is powered on and might begin
transmitting.
