When using the solder-soaked braided coax, bear in mind that it if you
flex it enough the solder starts to crack. Often you'll see the solder
first crack in the area where the shield intercepts the connector body.
If you are going to form a choke and leave it alone, that probably won't
be an issue. I don't have any experience using coax like this in an
outdoor environment, so I would be hesitant to wrap it around a stack of
toroids and then hang from the feedpoint of an antenna without some sort
of enclosure to protect it from the environment (and to provide
mechanical strain relief for the connectors). YMMV.

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
