A 16 Turn S-Band Helix - This design represents the smallest practical antenna for Oscar-13 mode-S. Perfect beacon reception at all times is possible, and acceptable SSB even at 43,000 km range.

13 cm Helix Antenna  ^pop - 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.

Design your Own Super J Pole - a Javascript for calculating the lengths of tubing to be used for the construction of a Super J-Pole.
