Parabolic antenna reflector for Potensic Dreamer

Parabolic antenna reflector for the remote of the potensic dreamer pro. 
I dont think it works for the potensic dreamer 4k, which uses the phone's wifi.
 

I use sticky spray and aluminum foil as seen in the picture.
I reached the 2000m distance limit with this reflector. Previously i only got like 1000m before the app complains of low signal. The last picture is a screenshot from the app showing the distance

Here is the parametric onshape file
