[MAMS] 47 GHz

[Dr. Gerald N. Johnson]

McMaster-Carr also carries those brass parts, and some in 3' lengths to 
save on splices for longer runs. www.mcmaster.com. Look for miniature 
brass tubes. They also have round metric brass tubes that can be handy 
for replicating European yagi designs on microwave. They don't admit 
they are K&S Engineering products that you find in hardware stores and 
hobby shops.
