Problem Possible causes Solution
No reception on any pola-
risation plane. Antenna position not cor-
rect Check the position of your
antenna. Use the signal
strength indicator of your
receiver (transponder info)
Still no reception on any
polarisation plane Short circuit in LNC
connection Disconnect the branch
connections on after the
other to locate the short
circuit
No reception, or wrong
programmes, on individual
polarisation planes LNC connections swit-
ched, or central wire in
connection too short Check on the allocation of
cables and connectorsr.
E.g. use a receiver to
check on the signal direct-
ly in the LNC connection.
Outputs of individual par-
ties not functional LNC voltage and/or swit-
ching criteria of receiver
incorrect Try connecting the recei-
ving unit to a different
party output.
Check the LNC power and
the switching criteria with a
measuring device, or try
another receiving unit
No reception via receivers attached to
cascade unit. LNCs not feeding in Set switch on 9/8 G to
“
Off ” for energy saving
