Directional vs. Omni-directional antennas

This 7 dBi gain panel antenna is directional. Antennas that come with Wi-Fi adapters are often omni-directional. Omni-directional antennas can detect signals from multiple directions and work best when you are mobile and do not know where signals are originating. Directional antennas concentrate gain in a particular direction. While the antenna does not need to be in a perfect line of sight, it needs to be pointed in the general direction. Because directional antennas work best in the direction they are pointed, in many cases you will detect more signals overall with your omni-directional antenna, but find that your directional antenna may get stronger signal strength to signals it is aimed toward.

Additional Features:
- Engineer-tested compared to other directionals on the market to ensure excellent performance
- ALFA-branded, the trusted name in wireless networking
- Complies with 802.11g standard for 2.4Ghz Wireless LAN
- Contains RP-SMA antenna connector
- Works with all 2.4 GHz Wi-Fi devices that have an RP-SMA connector, not just ALFA brand ones

It works

It wasn't made clear it was only the antenna. Otherwise I would have bought the upgraded model..


It works great for getting WiFi at my gate. Far better than an omni-directional antenna.
However, I just learned (from the Alpa website) that this is an indoor antenna. Where my application is outside. I wish the Rockland website had stated this.
