> Just a note --    The actual semi-rigid cable (silver plated copper tubing outer conductor 0.141" OD) that is being discussed RG-402 has an equivalent in a "conformable" cable. This conformable cable is the same construction except instead of solid copper tubing outer conductor it has a solder-soaked braid. Easier to work with and same electrical properties. Huber-Suhner produces one called "Sucoform" and another called "Sucoflex". I use the RG-401 size (0.250") for making short jumpers in my VHF/UHF station, using the same connectors made for RG-401 semi-rigid. These connectors are easy to find and not expensive, if you dig around a little. This 0.250" cable has very high power handling ratings at VHF/UHF.   There is a Chinese supplier of conformable cables on eBay. You can get both of these sizes with or without a jacket. The Huber-Suhner cable Sucoform has no jacket.Just some limited information from my experience,Byron W5FH


another brand name is Tensolite - although I think it's now called 
Carlisle MaxForm

"hand formable" is the key phrase.  The solid copper stuff is "sort of 
handformable, but it works better if you have a bending jig, 
particularly for 0.250 and 0.141 size"

Watch the bend radius on all of these. Maxform 141 has a minimum bend 
radius of 0.63 inches (another reason to use the little bending jigs). 
The solid copper version from Fairview (and Pasternack) has a bend 
radius of 0.25" ID (so a bit more, along the center of the cable).  
solid 141 is rated at 450W at 1 GHz.
