Thanks for your reply.
I've the same latitudine of ROME, but im on ADRIATIC SEA (ABRUZZI). I've a lnb MTI AP8... universal 0.6db, and i've regulated the skew at the best possible (little adjustmen and i lose the signal).
The dish is a 3 mt prime focus (2 piecesof fobreglass) made from Pellini in Italy(they say the on of the best in Italy ). I've a Panny 30 and 35 mt run cable.
Last week i was in CAMPOBASSO (MOLISE) below my latitudine about 50 miles.My friend have a 180 cm Channel Master, offset, alnb Twin 0.7-0.8 db and 20 mt of cable. I,ve connected my Panny and we can have the signal from the low frequency (from 11778 to 11939) and no signal fro high frequency. exactly the opposite of the my location ( i've the high freq, and no the low freq).
the signal of high freq is ok around 5 pm when i've ok the signal from low frequency.
For have the signal from 11778 i had move the dish of just millimeter and at 8.00 pm when the signal go away, i had the remove the dish for continue to have the other signal.
Why???????????
thank you.
