noise, To ground, connect a thick polyvinyl insulated wire to the GND
terminal and attach the other end to a metal water pipe or grounding
bar or wind it around a copper plate and bury it.

Never connect a wire to a gas pipe for grounding since sparks may ignite
the gas.

the orientation of the AM loop antenna, a separate indoor antenna, or
an outdoor antenna should be installed.
