ARR preamp problem

I bought the mast mount RF switching version of the ARR 70cm preamp this summer with the idea of upgrading the stations both at home and the vacation station. I had them install the choke so I could power it through the coax. It worked maybe once and very well at the vacation station and then was deaf as a stump. Switching it inline made no difference one way or the other. I sent it back and they put it on the bench for hours and then returned it when they could find no problem. We came back recently to the home QTH before I could try it again. I just swapped it out for the old, but working Mirage preamp. Guess what....it is deaf! I'm powering it through the coax as always. What could I possibly be doing wrong or missing here?

If both preamps are deaf, I'd check the connections to the antenna feedpoint. Mine cracked there years ago, making communication a challenge. Easy fix, however, once the problem was identified.
