Hypothesis:

Using a (DIY) parabolic reflector behind a cloverleaf antenna will increase the cloverleaf antenna's distance.

Discussion:

I saw a video on Youtube (still looking for it; I'll post it when I find it) that shows viewers how to builld a parabolic reflector for an antenna when I came up with the idea. Seems like the pair (parabolic reflector and cloverleaf) could work in theory. I understand the cloverleaf is an omni-direction antenna, but it seems in theory it should work nonetheless.

Just wondering if anyone has tried and succeeded (or failed). The idea would be (if possible) to add the parabolic-cloverleaf antenna to a servo-based bi-lateral tracker that would not only track the UAV signal from ground station but also track the ground station signal from the UAV. The benefit is that position of the antenna becomes less relevant. 

Feedback (even theoretical) is welcome.
