2-conductor shielded with teflon?

Post by greiswig »

Anyone have a good source for low capacitance teflon shielded with two conductors in it? Looking for something that can stand up to soldering better and can do there-and-back runs from controls to the board.

Thanks!

I have some -- well, not sure of capacitance. It is white on the outside, braided shield, one blue/white, one white conductor. It seems to be 22AWG but I'm no expert. I have several pieces in 15-16' lengths. USPS will be about $2 first class mail (guessing). Make me an offer? I'll sell it cheap. PM me.

Edit: Don't know if this is the right way to do it. Using my DMM, I get 0.92nf between the two conductors and 1.34nf or 1.36nf from conductor to shield. Is this useful info?

Currently using MIL-C-17 RGU-142 which has a solid copper, silverplated 18 ga conductor and a thick dielectric. About 30pF/ft. It is OK for short runs across the chassis but too big for four or five long runs a la Dumble, at least not in a smaller chassis. In a CE chassis, maybe. It's almost as big as a video cable.


I've also used the stuff Brandon used and some that Jelle Welagen uses. These I use where I can't run the RGU-142. Both about 30 pF/ft. Have very little of these left now.

Since I finished my Corksniffer's 5E8A Twin I am reassessing my use of coax ie I have been using too much of it in the past. I know the low power twin is not nearly the gain of a Dumble, but I did 8" runs of solid 20 ga hookup wire on the Twin, and it is as quiet as a mouse pissin' on a cotton boll.

You can also add me to the radar on this...
I have stock on this, If still interested contact me..
Oh.. Also have coaxial cable too...

I've purchased from this guy as well as Apex Jr. and had good dealings with both.
