Large antenna deployment
A 5 m-diameter antenna reflector, designed for orbital operations, seen during a test deployment during ESA’s latest Large Deployable Antenna Workshop.
Large-scale antenna reflectors are increasingly required for telecommunications, science and Earth observation missions.
This metal mesh reflector has a ‘double pantograph’ design to form a deployable ring. Once deployed it tensions two opposing, but connected, parabolic shaped nets, one on the top and one on the bottom.

If I made something like this in my garden, what science would it be useful for?
It's brilliant!
why hasn't EZ-UP patented this?
it's beautiful
This is what I suggested the ham radio boys start pioneering some years ago, but they couldn't get their head past the implied insult that their monopole antennas were inferior.
