Hello,
Is there a secret to putting coax connectors on RG-213?  I have to do a few and finding that it's a real tight fit.  After the cable is prepared (3/4" center pin and 5/16 braid) the coax screws into the connector real hard near the end and requires a pair of pliers to twist it all the way to get the tinned braid up to the holes.
Thanks,
Jim

While I've never encountered this problem myself, and I use RG-213 for all my outdoor runs, there is an old trick you might wanna try.

Just apply a little baby talc powder to the outside of the coax.

This happens primarily with the cheap, 99-cent PL-259s and or cheap coax. They may or may not conform to established dimensional specs.

Quality coax and quality (Amphenol) connectors almost never have these problems.

Lon,
The connectors are Amphenol and the Coax is Belden.
Can't get to much better then that.  Still a tight squeeze.  Possibly the roll of Belden I got didn't quite measure up to specs.  Have to crank the connectors on with a pair of pliers.
tnx, Jim

I've not run across any combinations that tight. I usually just rub a bar of soap on the jacket and the connector body screws right on.

Even heavy skin oil will lube the jacket. Smiley

Actually, I see that "problem" all the time and don't consider it to be a problem.

I do use "gas pliers" (slip joint pliers) to twist PL-259s on to RG-213/U and consider that pretty normal.

It takes four full rotations to twist a PL-259 on to RG-213/U, and the last twist can take a lot of torque.

It's worth it, since the resulting fitting is pretty waterproof.

hi,

I've also my vise grips to attach the connector,
just as steve, WB2WIK, described.

the coax I had was factory fresh from the wireman,
I did notice the connectors did attach easier several
months after the coax 'aged' in my garage.

Thanks for all repiies.  I managed to get the job done.  Had 10 to install.  Had to crank them all on with pliers but all turned out well.  I hadn't used any of the big stuff for quite a while and it seemed to me more of a struggle than I remembered in the past.
tnx agn,
Jim

A very, VERY, VERY,light dab of liquid hand soap, spread around the outer insulation of the coax, spread around, will make "screwing on" the PL-259 easier to install.  But remember, the whole purpose IS for the plug to "screw onto" the coax, for at least a semblance of weather resistance. and to form a seal to the outside environment.
