Products Features: 2.4GHz Frequency Range Directional Orientation for Precise Wireless Signals Weatherproof & Corrosion Resistant Product Description: The D-Link ANT24-2100 can be used to improve the transmission rate and extend the transmission range of your wireless LAN device operating on the 2.4GHz frequency range. The D-Link ANT24-2100 antenna provides extended coverage for an existing 802.11b or 802.11g wireless local area network (WLAN). Can be installed to a device equipped with an N Type connector. The antenna provides a very high Gain of 21dBi to give you an extended operating range. To achieve a desired operating range and transmission rate, antennas of the same Gain (21dBi) should be installed at both the transmission and reception ends. Transmission distances can vary according to the transmission speeds.
