LMR400 Ultraflex and connectors !?

[GrouserPad]

Ok, so I may have made a minor mistake. I ordered Ultraflex lmr400 to replace a 80 ft run of rg8x. I ordered connectors for lmr400. Are standard crimp on and solder lmr400 connectors not going to work with the stranded Ultraflexlmr400? One end is pl259 other is type n male.

As long as the center pin on the pl-259 is big enough to accept the center stranded conductor of the cable without a bird’s nest that shorts against the shield, you’ll be fine. You might want to tin the center conductor tip so it slides through the hollow center pin without any strands bunching up.

Ok, that’s kinda what I was thinking, but of course, after purchasing it I read multiple comments about only being able to use TC type connections which I assume means compression style like the Messi-Paoloni ones? Oof I may just cancel the order tommorow and reorder standard lmr.

I wouldn’t, but it’s up to you.

When all else fails, read the instructions rather than relying on online comments.  Here's the data sheet from Times Microwave:

While they do list TC connectors, they also list EZ connectors (third page of the extract) including the EZ-400-UM (https://timesmicrowave.com/connectors/ez-400-um-coax-connectors/).

Finally, here is information on the difference between TC and EZ. They do indicate TC for stranded center conductors. I’m sure that’s because forcing a stranded center conductor through the spring fingers probably causes a bird’s nest. Any soldered center conductor should be fine. Personally, I would use the crimp shield and soldered center conductor tip.
