Increase the effective range of your wireless network with the High Gain Antenna for SMA Connectors from Linksys. Attach this high gain antenna to your networking device, and increase both the effective strength of the outgoing signals, and the receive sensitivity for incoming signals. The added signal strength and sensitivity also improves close-range communication reliability, thus reducing retransmissions due to weak signal reception errors. The added signal strength and sensitivity also improves close-range communication reliability, thus reducing retransmissions due to weak signal reception errors. Featuring an omni-directional design for 360 degrees of coverage, this antenna is compatible with both Wireless-G and Wireless-B devices. The High Gain Antenna helps to build corporate wireless infrastructure by driving stronger signals into distant corners and hard-to-reach areas.
