When the receiver is operated with a paired transmitter, it sometimes happens that the
transmitting wave of own station is induced in the receiving antenna.
When the induction current of the transmitting waves is I ampere or less, the receiver is
protected by the built-in input protective circuit. But if the induction current exceeds I
anlpere, the input circuit of the receiver may be burnt out.
When the receiving antenna suf-fers fiom such an excessive induction current, move the
receiving antenna as far as possible trom the transmitting antenna, or insert the anti-inducer
in series betweetr the receiving autenna and antenna input connector as shown in Fig.3.l.
