Found some 30-year-old double sided copper perf board, cut a small piece to support the LNA in the box. Will solder the LNA to the perf board to mechanically support it and to provide a rock-solid electrical ground plane. Not sure it’s necessary but it looks better!

Pilot holes for connectors drilled. Maybe this time I’m closer…

A *while* later… had to notch out the circuitboard a little bit to allow me to get it in with the connectors already in place. Does appear solid and substantial.

Next, how trim down the LNA board to fit. See you soon!
