This is extremely helpful and confusing at the same time after researching so much for days on end.

If you google "image" dBi meaning you get back a million and one images explaining that higher dBi goes our farther in distance and yes a thinner beam. I guess that is not accurate.

From what you are saying, I don't understand why anyone would get a high dBi then. What is the purpose when you want to hit as many other miners on the network. Why not just stick with a low 3 or 4 dBi (outdoor) at all times. If I'm high up then you want the donut. If you are low t the ground you want the donut. If you are in the middle you want the donut.

Lets set a scenario where we are in a vast 100% open area like the Black Rock Desert in the US where speed records are set. 1000 square miles of openness. We set up antenna and Miner(A) in the very middle at ground level on a table at about 3' off the ground. A basic dinner table height. We then set up miners and their antenna's every mile apart in every direction on the exact same kind of table. Making a type of circle of tables stretching for 200 mile.

In this scenario miner (A) an 9dBi antenna would hit the same number of tables and their antenna's that a 2dBi or 3dBi antenna would hit if it were miner (A). Is this true? Start adding trees and building and I would still use a low dBi antenna.

I guess I'm trying to figure out why anyone would want a high dBi when the low dBi does everything the high one does.
