These rules apply to all types of stations, including base,
mobile, air-borne and marine. They are very important for

1. Install the transceiver as close to operation
site and power supply system as possible
(whether it is an external power supply or
battery system).
2. The antenna must be installed in an open
space and as far as possible from your
operating point. Example: on a sailboat use
the backstay as the antenna, since it is the
farthest point away from the rest of the
vessel.
3. The antenna coupler should be installed at
the feed point of the antenna.
4. Always create your own ground with radial
wire or copper straps. They are the only
ones that will guarantee a solid and proper
ground system.
5. All cables - power supply, control or coaxial
- must always be as short as possible and/or
necessary. Any excess cable should be
shortened to the proper length - never coiled.
Following these rules will minimize marginal installations
and problem sources such as RF feedback in the radio,
power supply or cables and “hot” or RF burning
microphones. If all 5 above points are followed during the
