I'll look into finding the right size tubing. It seems ridiculous to

I measured, recorded, and misplaced a table of dimensions for the
various RF Industries crimp sleeves. I'll dig when I get home.

If you order copper, make sure you get hard drawn copper, not soft.
Soft just doesn't have the holding power and will cold flow. Also,
note that there's a big difference in pipe and tubing. Pipe is
measured by the ID, while tubing by the OD. Note the comments on:

Also, I had some trouble cutting the sleeves as the tubing would get
mangled by my pipe cutter. So, I turned a round wood dowel to the
correct size and used it for inside support. Later, I used a lathe to
do the cutting, but that was overkill. The only problem with the pipe
cutter is that it tends to create a sharp edge, which when pointed
inward at the coax jacket, will badly gouge the coax cable. You'll
need to deburr the cut crimp sleeves, which is not easy.

Since none of the sleeves every carry RF on any surface, I saw no
reason to silver plate them. However, I did have some electroless
silver (Silver Cyanide) handy, so I did it anyway. Be sure to
degrease and acid wash the sleeves first. (Yeah, I forgot and they
look awful).

You might want to call or write RF Industries in case something has
changed in the last few years. If not, you may find it profitable to
sell sleeves and crimp rings on eBay.

I see Rat Shack sells crimp rings for RG-6.

I didn't have any luck finding crimp rings for RG-8.

Totally off-topic, but I installed NEC2. Man, what a stone-age piece
of software. 4NEC2 crashes under X64. The only one I could get to run
on my Suse box was nec2c. I ran Trevor Marshall's biquad in about a
minute. [I'll see if compilation flags can improve this.] This is
going to be a steep learning curve.

I'll start a new thread here should I have any wifi NEC2 questions,
but will most likely just join the NEC2 list.
