This 2.4HGz 7dBi Indoor Panel Antenna is a Directional antenna. It has an RP-SMA connector and can connect to many Alfa Network brand wireless USB adapters including the AWUS036H 1000mW USB long range Wi-Fi adapter. It can also work with other brand Wi-Fi adapters and routers/APs that have an RP-SMA port.

The above image is not a precise scientific comparison drawing, but an illustration to show in a general sense how the two antenna types compare. This 7 dBi gain panel antenna is directional. Antennas that usually come with Wi-Fi adapters are often omni-directional. Omni-directional antennas can detect signals from multiple directions. Gain is not concentrated in one particular direction. Omni-directional antennas 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 to the signal, it needs to be pointed in the general direction. Due to the way antennas work, directional antennas can pick up signals that are the in the opposite direction, but they will be weaker than if the antenna was pointed in that direction.

As the graphic above illustrates, each antenna type has an advantage over the other. That is why it is best to have each type, so you can use the antenna that is best for your particular needs. 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 at, and it may also detect additional signals in the direction it is pointed, signals the omni cannot see.
