Hey fella's (and ladies) I am getting ready to whip up a patch panel that will utilize barrel adaptors and a metal panel to lead outside. Does anybody know off-hand what the thread dimensions of a PL259 is so that I can buy some retaining nuts?

Every good quality "barrel" connector (1 thru 6 inches) I've ever gotten came with 2 nuts per "barrel".

Yeah RL I know but they are very thin, wimpy nuts. I was going to get a more robust nut that covers more than 2-3 threads :-) The ones I'm using are about 2" in length and are threaded the entire length. I think we are thinking of the same brand/type. I really don't care much for the ones that are molded and not threaded in the middle. Not only that but I get the good ones for free :-) This will be going on a metal panel on the wall and serve as a common connect point to the outdoors.... It's kinda a long story, the sheetrock is out of that area because I did something stupid :-) Instead of having several holes in the wall where grounding/coax comes in I'd like to tidy it up with what I have around the house + some nuts. If the flimsy nuts come loose it would a pain in dissasembly, in my expierience they either come loose or strip out from over tightening. Often times I use 2 nuts per side of the panel in a jam nut configuration, it DOES work that way but I'd rather not do that. I guess I could grab the connector and take a drive into Fastenall.

I think the nuts are rather whimpy because the construction of connectors is rather weak. Using a stronger nut would encourage folks to torque them well beyond their strength and deform or break them.

It would be nice to have more than two nuts per pass through though. And maybe include a washer for each side as well.

HP, I duno, the barrel is MUCH tougher than the nuts. I have seen some strange things happen to that barrel and it has come out well..... If I get a tough nut and strip the barrel it will be WAY too tight. Right now I use a SS ring with an allen lock to clamp it then the 2 nuts that come with it. It's OK but not ideal.

They (the barrels) are the ones we use on stage to lenghten IEM monitor antennas. KV knows them, the ones that come with the Shure Rack Mount kits. Every sound company has boxes of them :-)

they are a good brand; because they are used in a more profitable industry.
how come we get the cheap stuff?

chad, our sound guys hung the IEM antennas on the basement on the wall, and coiled up the coax underneath them.
i get a kick asking the new guys why they feel they need a choke balun.

"HUH!!!?"

For a while I was bucking the "iPod Movement" by using a full wave omni on an IEM transmitter up in the loft of the house attached to the computer. I then used the belt-pack and listened to the computer while mowing! There's a way around everything.
