Keep in mind that higher gain means more directionality and less wiggle room for height. So if a node is too far up or too far down from your elevation with a high gain antenna you may very well not be able to hit it. A low gain antenna is better if you do not know which direction your signal is coming from. A 3DBI antenna receives in a very spherical pattern at a slightly shorter distance, where a 10DBI antenna receives in a very flat pancake kind of pattern at longer distance, but cannot receive very low below the antenna and cannot receive very high above the antenna.
