Antenna height?

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, but the other better for less distortion in the video feed. I am using two helical antennas. I hope someone can shed some light on this.
