10 Connections - ANTENNA FM The ability to receive an FM signal may be diminished by terrain, area buildings, and the construction materials of the building housing the receiver. Keep these circumstances in mind when selecting the type of FM antenna and its mounting position. An indoor FM antenna is provided and should be suitable for most applications. Repositioning the antenna may be necessary to identify the optimum mounting location. If greater signal strength is required, replace the supplied antenna with a large outdoor FM antenna using 75 Ohm coax as the lead wire.
