Commentary
Indoor antenna exclusively for FM.
By combining a dipole antenna and a ferrite core antenna, the conventional dipole antenna of nearly 2m has been reduced to a 48 cm composite type.
In order to obtain high sensitivity and excellent selectivity characteristics which are the basis of an FM antenna, an LC tuning circuit is built in.
Conventional dipole antennas could not change their orientation once feeder wires were stretched on the wall. With FM-1, it is possible to turn the dipole antenna of the plate part after adjusting the tuning dial to the receiving frequency, so that the optimum receiving point can be found and the best receiving condition can be obtained for each receiving station.
Use the 75-ohm terminal of the tuner for connection.
