One of the things I haven't forgotten seeing in a museum
(Smithsonian?) 20 years ago was that ingenious-looking tube-ish beam
that rolls out of a small canister. It belongs in some Clever Gadget
Hall of Fame....

You're likely referring to Canadian STEM (Storable Tubular Extendible
Member) technology. First used in space aboard Alouette I back in 1962
(where it was used to implement two long sounding dipoles (150 feet
and 75 feet tip-to-tip)), STEMs have since been used on many space
vehicles. The version used aboard Alouette I was developed by Spar
Aerospace from a National Research Council of Canada design for an
extendible mast antenna from the WW II era.
