Why would you ever possibly need these connector "adapters".

I put it on my Magnum 257. It does help in mating coax up to hard to reach rigs. I like it.

We use these kinds of adapters to protect our precision connectors from excessive wear and damage in high use/aggressive environments.

This UHF connector, probably just as has been illustrated already...

If your co-ax shrinks a bit with age one or two of these can add back a little length to your feedline to maintain that magic 18 feet.
