2.5 Receiving antenna
Following antennas are suitable to use as the receiving antenna for the TF-711.
A) Antenna coupler TFM-01 + 2 m whip antenna (supplied by us as option)
B) Whip antenna (6 m ~ 8 m)

Note: Generally, whip antenna is suitable for reception over 6 MHz, and wire antenna is
suitable for reception under 6 MHz.
Receiving sensitivity would become worse when using one antenna for other receivers and/or
transmitters through multi-coupler. In that case, please use other antenna or install
exclusive antenna.
Be sure to connect BK especially for following case in order to avoid from burning trouble of
antenna coil/receiver circuit.
A) In case of using same antenna which is used for a transmitter
