helical

I've heard of Clover Leaf, Skew-Planar, and Helical antennas. Are all of these the same and work together or are they all different? I want to get into FPV, but it's stuff like this that is prohibiting me. Thanks.

Hello All, I am setting up a ground station for FPV. Doing reseach and found some guys have low to the ground antennas. And others high. I am making my system around 5.8MHz. Do each frequency have a different optimal height that the antennas work better. Or one height better for long distance...
