Hi there. Does anyone know of a good way of testing terminations on LMR cable? It seems that too often we don't have good connections as a result of improper terminations.

If you have a network analyzer handy, you can terminate one end of the cable path and flex the cable, shake/twist the connections, etc. Any problems would show up as return loss variation.

Otherwise, you can disassemble all the connections and check for contamination, broken or scratched contact areas, etc. Lots of problems are caused by poor mechanical connections.
