NOTE
About FM waves:
FM waves have the same properties as light, and
can be deflected and blocked. Wave reception is
not possible in the shadow of obstructions such
as buildings or mountains.
1. The signal becomes weak as the distance from
the station’s transmission antenna increases.
Although this may vary according to the signal
strength of the transmitting station and
intervening geographical formation or buildings,
the area of good reception is approx.
km (12-16 miles) for stereo reception, and
km (19-25 miles) for monaural
reception.
