Flexible, small diameter coax...???

Tieftoener · 18th November 2003, 02:25 PM

Hey all...

I'd really appreciate some help. I'm looking for some really flexible, small diameter coax cable to be wound up on a 1.5" spool. I've been looking around at the 300 level RG types. I'm curious if there's any with a NON-solid core... a stranded center core type. Impedance will be customer dependant - 50 or 75 ohm... not sure yet.

The reason I'm interested in the stranded core is for long-term durability from bending constantly to be wound up on a spool. Application is for a project at work that would really make things easier.

I have always assumed that the cables on the probes from my Tektronix TDS2012 scope are coax... but they have no marking on them. They are a good place to start for flexibility.

Any places or suggestions to start would be a big help. We will be ordering A LOT of this cable (many thousands of feet) on a regular basis, so please keep that in mind.

Your help is appreciated - thanks to all!!

RG174 ( 50 Ohm ) or RG175 ( 75 Ohm ) ?? Both are flexible and 3 mm in diameter.
