AFAIK, the 1st gen. digital SWiM 3 LNB of which there was only one, the "3D1LNBR0-01", was mfr. by WNC and is not RB capable.And all these different generations were WNC ?
I'll have to look at mine, but I think it's 1st gen.
The 2nd gen. non-RB digital SWiM 3 LNB of which there was also just one, the "3D2LNBR0-02", is mfr. by Pro Brand (the Eagle Aspen Co.)
The 2nd gen. RB digital 3 LNB, "3D2RBLNBR0", has three mfrs. with "-01" (WNC), "-02" (Pro Brand), and now a "-14" (unknown) suffix.
The 2nd gen. RB digital 5 LNB, "5D2RBLNBR0-01" only has one mfr. WNC.
