Loop configuration
In this configuration, antenna signal is passed by only one coaxial cable and the connection between tuners is
created internally. And satellite signal has to be connected to the first tuner (ANT 1 IN) (near PCMCIA slot).
This configuration introduces minor limitations when both tuners are used at the same time.
The limitation is connected with polarization and lo/hi band. E.g. when the first tuner (ANT 1 IN) is tuned
to TS with Horizontal polarization, LNB sets 18V, and the second tuner (ANT 2 IN) is connected to TS with
Vertical polarization LNB sets 13V. But it is not possible to have 18V and 13V on single cable, so 18V is set. It
means that the second tuner (ANT 2 IN) cannot be tuned to TS and no signal is observed.
In this case, functionalities like PIP or Double-REC are restricted to services with the same transponder
polarization (Vertical/Horizontal, Tone On/Off).
