I have been using RG400 to make jumpers for years. It is a nice easy to work with coax that has excellent shielding. RG400 is available surplus for much less than $5/ft.

I compared the specs and found they're virtually identical, the only significant difference being that RG-400 has a stranded center conductor, while RG-142B has a solid steel (silver-plated) center conductor. They both have a 1 inch minimum bending radius (for repeated bending), but I imagine the RG-400 Is slightly more flexible and the RG142B is slightly stronger. At GHz frequencies, the RG142B has slightly lower loss. They both have excellent high temperature properties. If you buy it new from a distributor, either will cost about $5 a foot. 73, Jim w8zr _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
