Yamaha RX-V667 Owner's Manual page 32

An indoor FM antenna and an AM loop antenna are supplied with this receiver. Connect these antennas
properly to their respective jacks.
Indoor FM antenna
AM loop antenna
Position the AM antenna away from the
receiver. The wires of the AM antenna have
no polarity.
You can connect either wire to the AM jack
or the GND jack.
• Improving FM reception
We recommend using an outdoor antenna. For more information, consult the nearest authorized
dealer.
• Improving AM reception
Connect this unit to an outdoor antenna with a 16.4 - 32.8 ft. (5 - 10 m) vinyl-coated wire. Make
sure the AM loop antenna is still connected.
Connecting the GND jack can reduce noise. Connect the jack to a store-bought ground bar or copper
plate with a vinyl-covered wire and bury this new attachment in moist ground.
The GND jack is not to be connected to the ground socket of an electrical outlet.
