. Input signal regulation
manual retuning of some channel paths might be needed. This might happen in several cases:
from the same antenna – in this situation it’s recommended to “move away” filters from each one
Reflection appearance (two images occurring – the correct one and moved one ), caused by
receiving strong signal near weak signal from different antennas – in this situation it’s recommended
