■ FM outdoor antenna
Consult with your dealer or service man about the best
method of selecting and erecting an outdoor FM antenna,.
The choice of lead-in (feeder) wire is also important. The
flat ribbon-shaped twin lead performs well electrically, is
cheaper and is somewhat easier to handle in routing
through windows and around rooms. Coaxial cable is
more expensive, does a much better job of minimizing
interference, is less prone to the effects of weather and
close-by metal objects, and is nearly as good a signal
conductor as the ribbon type wire. The latter is particularly
true of foam-type coaxial cables. Coaxial cable is some­
what more difficult to install at the point where the cable
enters the building.
■ FM outdoor antenna setting
• To minimize auto-ignition noise, locate the antenna as
far from heavy traffic as possible.
• Keep the feeder or coaxial cable as short as possible.
Do not bundle or roll up excess cable.
• The antenna should be placed at least two meters (6.6
feet) from reinforced concrete walls or metal structures.
■ T-shaped FM indoor antenna
The T-shaped FM antenna shall be used as a preliminary
for the period before a dedicated FM outdoor antenna is
installed.
