MOOKEERF RG8x SO239 Crimp Connector - UHF Female Coax Adapter Connectors for RG8X/ LMR240/ Mini8/ 4D-FB Coaxial Cable (Pack of 5)

These SO239 have worked great so far. I’ve used 5 of them so far for various coax jumpers and they seem to be of good quality. We’ll see how they hold up over time. I would avoid the PL259s from this seller though as the threads on all ten of the connectors I received were bad.

Overall quality on these is great and so far the company has created great value for the money and has relatively easy installation and cost-effectiveness!

The heat shrink should be three times as long but I have some longer heat shrink in my possession and was able to use that for these. Easy to use and good fit.

They seem very good and will probably need some instructions as how to make them up

Works like it should.

Work perfectly

Look like good connectors. We will see when I build my next cable

I used an on-line instruction video for assembly, it came without instructions, otherwise I would have rated it a “5” . I suggest you apply some soldering flux to the center conductor before sliding on the center pin when you solder. Do not overuse solder and apply the iron with a drop of solder directly to the tiny hole in the side of the pin. Use good solder technique, keep your parts clean. I made a common mode choke with these connectors to avoid using female-to-female connectors to connect my cables. Extra connectors mean higher losses.
