[MLB-WIRELESS] Best Radio and Antenna Gain Configuration?

[Michael Nardella]

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 
at most.

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.
