i will attach another lnb to the set up... currently prime focus is AsiaSat 3S, and one side lnb is tuned to AsiaSat 5.... ChinaSat 6B will be an addition to the multilnb set up...
Biswajit, you can try waving the LNBF at the top of the dish in the opposite direction, considering the Chinasat6B beam is incident on the dish from the lower side.
Keep a Chinasat 6B transponder channel on while waving the LNBF. Once the signal is found, tie the LNBF to the support arms of the dish.
