NASA antennas.

Just surfing around. Came across some interesting designs.

Talk about neat.

Neat!

Thanks for that post.

That small connector monunted antenna reminds me of the paperclip I once used as a makeshift to test a used commercial VHF transceiver.

Seems that although the design is counter intuitive it is suprisingly good at its job. It is of course for extremely high frequencies in the 7 and 8 Ghz area.

Don't forget that NASA's goal may be different than yours.
They have to beable to receive a signal of unknown polerazation ariving at an unknown angle.

We have the luxery of receiving (mostly) vertical polerized signal from the relitive horizon.

Diffrent needs drive different solutions.

Oh I wasnt thinking these for scanners. Just a neat little thing to see. Maybe it should be moved to the Tavern. Just something I cam across while searching.
(See I am searching lol)
