Yamaha HTR-6180 User Manual

Both FM and AM indoor antennas are supplied with this 
unit. Connect each antenna correctly to the designated 
terminals. In general, these antennas should provide 
sufficient signal strength.

• The AM loop antenna should be placed away from this unit.
• A properly installed outdoor antenna provides clearer reception 

than an indoor one. If you experience poor reception quality, 
install an outdoor antenna. Consult the nearest authorized 
Yamaha dealer or service center about outdoor antennas.

• The AM loop antenna should always be connected, even if an 

outdoor AM antenna is connected to this unit.

Ground (GND terminal)
For maximum safety and minimum interference, connect the 
antenna GND terminal to a good earth ground. A good earth 
ground is a metal stake driven into moist earth.

Outdoor AM antenna
Use a 5 to 10 m (16 to 33 
ft) vinyl-covered wire 
extended outdoors from a 
window.
