A Portable Antenna for Mode B and J Satellites
In my case, I had been working SO-35 with a 1/2 wave on 70cm and a 1/4 or 5/8 wave on 2m. With these antennas and a little planning, it is possible to work this bird from a train

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
6 element yagi for 144 mhz
With almost 10 DBd gain, we have an Effective Radiation Power ERP 10 times greater of the tranceiver maximum output without Coaxial-Loss
A Helix antenna for 2 metre satellite
Construction of the helix antenna is mechanically a little more difficult than a Yagi and requires a reflector behind it to function properly
