site and power supply system as possible

(whether it is an external power supply or

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
