Replacing your WiFi antenna with This Alfa Antenna will significantly increase the range and strength of your WiFi signal. Our quality panel antenna is a direct replacement for the antenna that comes standard with your router, access point, VOIP device, or PCI card. it can send and receive WiFi in all directions. This Alfa antenna is stronger then the less powerful booster antennas offered by major manufacturers (Linksys HGA7S and HGA7T.) Installation is very easy - just twist off the factory antenna and twist on our Booster Antenna and you'll experience an instant jump in. PLEASE NOTE THAT THE INCREASE IN SIGNAL STRENGTH DEPENDS MOSTLY ON YOUR ROUTER OR ADAPTER THIS HELPS TO BUT IT CANNOT TRANSMIT OR RECEIVE POWER THAT YOUR MODEM OR ADAPTER DOES NOT HAVE!!! IT JUST GIVES MORE RANGE NOT STRONGER POWER!
