ANTENNAS FM Antenna If experiencing poor FM reception while using the accessory antenna, the use of an outdoor antenna exclusively for FM reception is l ikely to improve FM reception. The connecting wire between the antenna and the antenna input terminal is cal led a feeder. Most feeders are 3000 parallel or 7552 coaxial cables. We recommend type 3C-2V or 5C-2V 7512 coaxial cable to be used with this unit to enable it to perform to its fullest capacity. The coaxial cable has a stronger resistance against loss and interference compared to a parallel feeder. If there is a lot of noise while receiving an FM broadcast, we recommend that you make a ground connection. Connect one end of a thick wire to the antenna GND terminal and wind the other end around an earth bar or earth plate and drive it into the ground.

AM Antenna The AM loop antenna attached to this unit al lows sufficient reception, except in an area where AM signals are weak. In a fringe area or inside a concrete building where the reception is weak and the sound quality is poor, an outdoor AM antenna is l ikely to improve reception. Place the AM loop antenna as far away from this unit as possible, e.g. hang it on wall, without touching a metal object. You may also install the AM loop antenna by fitting it onto the antenna holder on the rear panel. To remove the AM loop antenna from the unit, simply pull it out of the holder.
