However, it depends on what you are trying to achieve. The higher gain
(assuming it is directional)is great for point to point, but would be
useless for connects from multiple geographic locations. A 20dbi gain
directional is probably going to have a pattern of 5-10 degrees width
I still put the better antenna over an amp/ rx preamp anytime. Just
have to pick the most appropriate antenna and the highest clear view of
the other end.
