A FM Antenna Connect an outdoor FM antenna to the FM 75Ω socket. Generally, a 3-element antenna will be sufficient; if you live in an area where the FM signals are particularly weak, it may be necessary to use one with 5 or more elements. If standard FM broadcast frequencies are available via your cable service, you may connect your 75 ohm FM antenna jack to your cable system. Please contact your cable service to discuss this option.
