Which Antenna Should Is Best?
There is no easy answer. Every setup/location relies on the neighboring setup, meaning trees, tall buildings, urban/city, number of miners near you.
To better understand which type you need, please take a look at the image below depicting the different dBI signal coverages.
2dbi = wide, short range at 360°
5dbi = narrow, medium range at 40°
7dbi = a bit more narrow at greater distance at 30° (most likely to skip closer witnesses)
9dbi+ = furthest distance at 25°, not wide (most likely to skip closer witnesses)
The lower the gain, the better the coverage, at 2dbi, you get 360° coverage, but at 5dbi, it drops down to 40° then 7dbi is 30°.
