Antenna Channels on BTL AM Board
TX Fig8 and Loop sockets connect to
the two types of coil antennas. They
must not be transposed; strictly
follow the sockets identification.
Some pedestal types may have
internal auxiliary RX coil antenna and
connect to this socket.
Tips:
The ferrite channel phase switch is
useful when sometime install run into
high noise environmental and two
ferrite rod antennas may have
additive noise value to block up the
RX channel. Switch the phase may
bring noise down.
