4.0 Five Golden Rules of HF Installation
These rules apply to all types of stations, including base, mobile, airborne and marine. They are
very important for planning and installing your HF system, if you want to achieve good
communications.
1. Install transceiver as close to operation site and power supply system as possible
(whether 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 base/feedpoint of the antenna.
4. Always create your own ground with radial wire or copper straps. They 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. An 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 five
of the above points are followed during the design and installation of your HF system, the
operator can expect top performance. Further information regarding applications, installation
