FM Lead Antenna
FM Indoor Antenna
If you live reasonably close to a transmitter and want to use the provided lead-type FM antenna, connect it directly to the FM 75Ω socket.
Fit the metal sleeve of the lead-type antenna over the core (center) conductor of the (FM 75Ω) socket, extend the lead, and attach it to the window frame or wall with thumbtacks or something similar in a location where reception is best.
FM Outdoor Antenna
In an area where FM signals are weak, it is necessary to use a 75Ω unbalanced-type outdoor FM antenna using the optional matching transformer, as shown in your user manual. Generally, a 3-element antenna is sufficient.
Connect the coaxial cable of the antenna to the matching transformer as shown in your user manual.
After completing the connection, plug the transformer into the FM 75Ω socket.
