RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

LMR-400 - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including 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.
