So a old installer friend of mine from Florida was passing through last week and brought me a box of C and Ku feeds and LNBs. all brand new. Norsat and California Amp LNB's and one thing that caught my attention. I see a box that says CalAmp on it and never new they made feeds. Opened it up and it had the CalAmp sticker on it. C and Ku polarotor but had ADL stampings all over it. Question is, I seem to remember hearing there was something special about them, is there? I might be thinking of a dual ortho they made.
