Radio reception is not possible unless the
antenna is properly connected.
The strength of broadcast signals varies from one area to
another (signal propagation is especially poor in metropol-
itan areas, where there are many tall buildings, and in
mountainous areas). Proper antenna installation is vital to
good reception.

External FM antenna installation
Use an external antenna when the signals trom the station
are weak and cannol be picked up by the accessory T-type
FM antenna, or when the sound heard is accompanied bV
large amounts oI noise. There are lwo ways of connecting

300-ohm feeder wire, or with a 75-ohm coaxial cable.
It is recommended that you use the 75-ohm coaxial cable,
so that the effects of extraneous noise are reduced to a
