The Booster Antenna is the most popular antenna that we offer and is great for people that don't want to do an outside installation.
The Booster Antenna improves signal for voice and data (1xRTT, EVDO Rev-0, EVDO Rev-A, EDGE [AT&T 2G], HSPA [AT&T 3G], WiMAX [Sprint 4G]). The signal "gain" users see with the Booster Antenna is variable and dependent upon available signal in the area, interference, etc. Be sure to read "Will an Antenna Help Me?" to determine if the Booster Antenna will work for you.
