Antenna and antenna mount
The most important activity in setting up a radio transmitter is determining the placement
and type of the antenna. Where flexibility permits, always place the antenna on the highest
point available and always select an antenna with a gain pattern (more on this later) which
optimizes the coverage. In general, use a directional gained antenna such as a Yagi for a
point-to-point fixed location application and a gained omnidirectional antenna for mobile
point-to-point or point-to-multipoint communication systems.
Note – Safety Concerns
- Be aware of power lines or other obstacles that can inadvertently come in contact with the
antenna and cause potentially lethal conditions.
- Guy-wire antenna masts higher than 10 feet.
- Use lightning arrestors for equipment and personal protection if erecting an antenna in
areas prone to lightning.
- Installation of antennas on buildings or other structures (towers, etc.) must be done in
accordance with local building regulations. Contact a local antenna installer who is familiar
with building codes and proper antenna installation for any permanent installation.
