The Fundamentals
Antennas
• The antenna stands between you
and the rest of the world.
• It has to deliver when you need it
most.
• Radio – Telephone - Internet
Typical whip antenna radiation pattern
The higher the gain, the narrower the beam
The effect of heel on transmission
Distance to Horizon
Yacht A (10 m) - 11.3km (6 NM)
Yacht B (20m) - 16 km (8.6 NM)

Antennas
• Antennas are matched to a band
(Frequency range)
• VHF and higher bands operate on
the basis of "line of sight"
• Gain, radiation pattern and position
of an antenna are important.
