I'm currently using a 75cm starchoice dish with a BEV LNBF. My dish can catch both birds with a decent amount of signal. I've just checked transponder 32 on nimiq 2, the result was superb! 90% on most of the Nimiq 2satellite. I believe you should upgrade to a larger dish like mine. A dish can play a big role in how well your receiver might perform in rough weather.
