6 GETTING STARTED
6.1 ABOUT VHF RADIO
The radio frequencies used in the VHF marine band lie between 156 and 158
MHz with some shore stations available between 161 and 163 MHz. The marine
VHF band provides communications over distances that are essentially “line of
sight” (VHF signals do not travel well through objects such as buildings, hills or
trees). Actual transmission range depends much more on antenna type, gain and
height than on the power output of the transmitter. On a xed mount 25 W radio
transmission expected distances can be greater than 25 km, for a portable 5 W
radio transmission the expected distance can be greater than 8 km in “line of sight”.
6.2 SELECTING AN ANTENNA
Marine antennas are made to radiate signals equally in all horizontal directions,
but not straight up. The objective of a marine antenna is to enhance the signal
toward the horizon. The degree to which this is accomplished is called the
antenna gain. It is measured in decibels (dB) and is one of the major factors
in choosing an antenna. In terms of effective radiated power (ERP), antennas
are rated on the basis of how much gain they have over a theoretical antenna
with zero gain. A 1 m, 3 dB gain antenna represents twice as much gain over
the imaginary antenna.
Typically, a 1 m 3 dB gain stainless steel whip is used on a sailboat mast. The
longer 2.5 m 6 dB berglass whip is primarily used on power boats that require
the additional gain.
3dB
6dB
9dB
6.3 COAXIAL CABLE
VHF antennas are connected to the transceiver by means of a coaxial cable
– a shielded transmission line. Coaxial cable is specied by its diameter and
construction.
For runs less than 20 feet (6 m), RG-58/U (about 0.25" (6 mm) in diameter),
is a good choice. For runs over 20 feet (6 m) but less than 50 feet (15 m), the
larger RG-8X or RG-213/U should be used. For cable runs over 50 feet (15 m)
RG-8X should be used. For installation of the connector onto the coaxial cable
refer to the gure.
6
To get the coax cable through a tting and into the boat’s interior, you
may have to cut the end plug off and reattach it later. Follow the directions that come with the connector to attach it. Be sure to make good
soldered connections.
6.4 DISTRESS AND HAILING (CHANNEL 16)
Channel 16 is known as the Hail and Distress Channel. An emergency may be
dened as a threat to life or property. In such instances, be sure the transceiver
is ON and set to CHANNEL 16. Then use the following procedure:
1. Press the microphone push-to-talk switch and say “Mayday, Mayday,
Mayday. This is , , ” (your vessel’s name).
2. Then repeat once: “Mayday, ” (your vessel’s name).

6.5 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)
Channel 16 may be used for initial contact (hailing) with another vessel.
However, its most important use is for emergency messages. This channel
must be monitored at all times, except when actually using another channel.
It is monitored by the U.S. and Canadian Coast Guards and by other vessels.
Use of channel 16 for hailing must be limited to initial contact only. Calling should not exceed 30 seconds, but may be repeated 3 times at 2-minute
intervals. In areas of heavy radio trafc, congestion on channel 16 resulting
from its use as a hailing channel can be reduced signicantly in U.S. waters
by using channel 9 as the initial contact (hailing) channel for non-emergency
communications. Here, also, calling time should not exceed 30 seconds but
may be repeated 3 times at 2-minute intervals.
Prior to contacting with another vessel, refer to the channel charts in this manual,
and select an appropriate channel for communications after initial contact. For
example, Channels 68 and 69 of the U.S. VHF Charts are some of the channels available to non-commercial (recreational) boaters. Monitor the desired
channel in advance to make sure you will not be interrupting other trafc, and
then go back to either channel 16 or 9 to make initial contact.
When the hailing channel (16 or 9) is clear, press the PTT switch on the mic and
state the name of the other vessel you wish to call and then “this is” followed by
the name of your vessel and your Station License (Call Sign) then release the
PTT switch on the mic. When the other vessel returns your call, immediately
request another channel by pressing the PTT switch on the mic and saying “go
to,” the number of the other channel, say “over” and release the PTT switch on
the mic. Then switch to the new channel. When the new channel is not busy,
call the other vessel.
After a transmission, say “over,” and release the microphone’s push-to-talk
(PTT) switch. When all communication with the other vessel is completed, end
the last transmission by stating your Call Sign and the word “out.” Note that
it is not necessary to state your Call Sign with each transmission, only at the
beginning and end of the contact.
Remember to return to Channel 16 when not using another channel. Some
radios automatically monitor Channel 16 even when set to other channels or
when scanning.
6.6 Accuracy of COG
The error in the COG (the path of the antenna position over ground) due to the
actual ship’s speed over ground shall not exceed the following values:
Speed range (knots) Accuracy of COG output to user
0 to ≤1 knot Unreliable or not available
>1 to ≤17 knots ±3°
>17 knots ±1°
