Lest we not a forget a fairly short helix 5-10 turns. Would probably be good enough for AO-51. Depending on ones construction methods, it could be fragile. They are easy to build and fairly "forgiving" 73 Bob W7LRD

I am trying to come up with a portable sat station that can fit in a briefcase. I have the dipole and reflector antenna that K5GNA sells for his downconverter but I am looking for something compact that can fit in the briefcase and the reflector cant.

See my foldable S-Band 1 meter dish Portable: http://www.ew.usna.edu/~bruninga/ao40ant.html

You can make it out of simple aluminum roof flashing.
