4.2  Transmission Range

Because VHF signals travel in a straight line
and are not reflected back off the ionosphere as
lower frequency signals are, the range of VHF
signals is limited to ‘line of sight’, beyond
which the other vessel passes behind the curve
of the Earth.  Therefore, the range will increase
greatly the higher above sea level the antenna
is, as Fig 5.1 illustrates (assuming maximum
transmission power is used):

Fig 4.1 - VHF transmission range

Therefore, the typical ship to ship range of a
fixed VHF radio such as the RT1200/RT1400
with a masthead antenna will be approximate-
ly 20 Km (12 miles).  This will increase as
height above sea level increases, or if the other
radio user’s antenna is at a greater height - note
that the range between the yacht with the
antenna mounted on a 9 M (30 Ft) mast and the
shore station increases to 46-53 Km (29-33
Miles).
