[Mesh] Satellite dish antennas

[Miguel Vargas]

I have 3 satellite TV dishes I can donate. One is a round Dish Network dish
that says "500" on it, another is a small round DirectTV dish, and the
third is a bigger oval-ish DirectTV one that says "Slimline" on it.

I'd never heard of these types of dishes used for 2.4GHz wifi, but reading
online it seems people are having success with them. Here is a project were
they used these types of dishes to detect wifi 8 miles away by replacing
the feedhorn with a custom soldered "biquad" antenna,
