The stated value of 2150 on the Holland is good enough to work. The bigger concern is the 2A rating. That prevents any accidental burnout caused by a powered switch (such as a DPP 44). I got your IM and sent you a link. Hope that helps.
Hmmm.... since I'm not using the DPP 44 powered switch ( it's not needed with the DPP Twin LNB and the DP Dual LNB, it has an internal switch ), should I still go with the 2A Blue Holland diplexer....?
