What needs to be considered?
Which type of antenna(only self-made or reused parts, for example satellite dish) is the best for a long range, high throughput WiFi? How to calculate Antenna size and shape? Which characteristics of the WiFi Module play a role for this application?
Long-Range WiFi for LOS.
You can share also any results of your own application.
A 2.4Ghz parabolic dishes reflect into/from a 12.5cm yagi pointed at the centre. I suppose you could be flexible with the dish diameter, but the yagi must be correctly made ( with reflector and director ), and you can't expect good results long-range with a yagi shorter than one full wavelength. If you are in an area with much traffic on 2.4GHz, use 5GHz instead. Ubiquiti networks used to sell pretty good cards for long-range links, but I suppose you can get by with some Alfa USB cards on the endpoints. Remember to use coax for antenna cables.

Tomato *WRT, whichever is most effective.
