8 beta-17. I replaced the pair of 19 with a pair of PBE-5AC-300 and the link works just as expected. After looking at the antenna patterns of the 16's and 19's it looks as if the beam is to wide with overly large side lobes, so most of the Tx power is being wasted on a PtP or PtMP that is over .5 miles long. Seeing as the cost of the 300 is with in a few bucks of the 19's we are going to only use the 300s.
