LMR-400 - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.

thanks
kevin

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.
