2.4 GHz Helix Antenna

Here is the design of a 2.4 GHz antenna that is ideal for amateur satellite communications. This antenna is easy to assemble because the design itself tolerates inaccuracies in the construction without really affecting performance.

And with this antenna, you won't have any difficulties working all current and future amateur satellites offering the 2.4GHz. band. An exception though is AO-40, which requires a parabolic antenna.
