Transformers for Receiving antennas:
When a long feeding cable is necessary, a transformer is
recommended to compensate for the signal strength loss
in the cable. A transformer is also recommended if the
antenna is used mainly on low frequencies.
The transformer is mounted on a circuit board that is
easily installed. For specifications please refer to separate
datasheet.
Mechanical specifications:
End feed, side feed receiving
antennas.
