Alfa APA-M04 7 dBi gain RP-SMA directional RP-SMA panel antenna

Alfa APA-M04 is a 7 dBi gain directional panel antenna with an RP-SMA antenna connector. This can connect to many Alfa Network brand wireless USB adapters. This will also work with other brand Wi-Fi adapters and routers/APs that have an RP-SMA port. This item is brand new. They come to us in OEM bulk packaging from Alfa so there is no retail box, it is just the antenna itself as pictured (the pictures show the antenna attached to an Alfa wireless adapter, which is not included in the purchase). Also there are no instructions, and that is because none are needed- you just screw it on to your Wi-Fi adapter's RP-SMA port and you are all set to go.

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. 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. 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.
