7mi WiFi connection

The apartment I'm at has included internet, and it's quite good compared to what my parents can get. They live 7 miles away as the crow flies.

What are my chances that I could get a decent connection 7 miles away to my parents house by mounting a directional antenna from the 3rd floor balcony of the apartment to my parents house on a hill?

What are my methods of determining if there is line of sight? I have a fairly powerful green laser. I've also got a telescope.

I'd be willing to climb one of the large doug fir trees and mount a directional antenna and router to it. Got any antenna recommendations? I've got a couple satellite dishes laying around.

Seems like a fun project anyhow.

EDIT 1:

Just found this website for determining line of sight:

https://www.scadacore.com/tools/rf-p...line-of-sight/

Here's the analysis based on the GPS coordinates I took from Google Maps:



The blue point is my apt, and the green point is my parent's house. This does not factor in that I'm 30ft up in the apartment, or that I would be mounting to a tall tree on the property. It seems my biggest priority is mounting as high as possible at the apartment.

Apparently there is a product from Ubiquiti Networks called the PowerBeam M5 AC that is rated to 25 km.

EDIT 2:

The elevation chart shows a ground level at the apartment of 70.4m. The first hill peaks at 84.75m. The tallest hill is at 88.27m. My parents at the ground are at 84.83m.

I figure the balcony is about 10m from the ground, which has me just 4m short of clearing the first hill. Perhaps I could get the antenna at my parents house 30m up a tree. It would be darn close to clearing that first hill (and all the rest of them).

EDIT 3:
