Thanks for the offer of help Greg. Think we figured these things out already, though. Found out that if we removed the NFIK, and jumpered for RF and voltage, these things act like regular maggie tna's again. Guess I should have been more specific in my question. Wanted to keep amps active using old trunk line while we swapped out some even older pizza boxes. Man, you gotta love old "unsupported" gear!
