## Description

The Alfa 2.4GHz 9dBI Powerful antenna is compatible with Alfa-AWUSO36H/AWUSO36NH/AWUSO36NHA/AWUSO51NH and many other Alfa wifi adapters. GET READY TO BOOST YOUR POWER.

Review: Very good - Swapping the tiny default antenna with this resulted in a major signal boost in my case.
Review: Ero scettico... - Quando mi hanno consigliato questo prodotto ero parecchio scettico in quanto da ignorante non sapevo cosa volesse dire 9dbi ma quando l'ho testata non ne faccio più a meno. Questa antenna permette (a campo libero e senza niente che ostacoli il segnale) di raggiungere segnali wifi ben più lontani di quelli dei vicini di casa. Testato in campagna dove c'è poco inquinamento del segnale ho raggiunto (con due tacche su 4) il wifi della cascina vicina( che è a circa 700m)
