Deker, that is the one that used to be in the OGN installation manual. I shied away from it as one of the responses to a question implied it was not suitable for SMA connectors. I assume it worked for you?
There are lots of crimp tools out there, many will do the job. The problem is that they may not state explicitly that they are compatible with RG8X to SMA terminations, which makes it a lottery to find one. Trial and error could be expensive in connectors and crimp tools.
