Pros
I went from a 4dbi omni antenna to a 14dbi yagi antennae and have dramatic improvement with this TPLINK 24dbi antennae. Its well worth the cost considering you can purchase it on a consumer level.
Strength is the strength of the signal! I went from 11-14 dbi connections to 19-22 dbi on tplink wireless connection utility; Antenna itself is made of steel and the bracket to mount it is heavy gauge aluminum; Weight together is easy to handle
No instruction manual to show how to put it together but its self explanatory with a bit of common sense and simple looking at the final product in any picture; NOTE: If your connection speed is always 3megabits p 70 ping don't expect that aspect of your connection to increase...
