There are two ways of connecting the FM antenna to the antenna input terminals: with a 3OO-ohm twin-lead feeder or with a 7S-ohm coaxial cable. lf full justice is to be done to the tuner's performance, a 7S-ohm coaxial cable is reommended since it is more immune than the twinlead feeder to noise and interference from external sources. lf an FM antenna has already been erected outdoors, connect it, referring to the
