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

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 including the AWUS036H 1000mW USB long range Wi-Fi adapter. 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

For this it is helpful to refer to image 4 up top. That 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 our 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.

- Alfa-branded, the trusted name in wireless networking- not a generic antenna
- 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

FAQ- some common questions about Alfa 7 dBi directional antenna kit:

I pick up 6 signals with a 5 dBi omni-directional antenna I have but only 4 signals with this 7 dBi panel antenna- is something wrong with the panel antenna?
-The panel antenna is a directional antenna that concentrates gain in the direction it is pointed. It does not pull in signals equally from all around, but should pull in better range and signal in the direction it is pointed. So you may see more signals overall with the omni, but the directional one will help you get the best signal to one in particular.

Whether I use a 5 dBi omni antenna I already have or this directional one, I see 3 signals, and all of them have the same number of bars in Windows. How can this be?
-antenna placement is very important. Wi-Fi signals bounce around and can be impacted by invisible interference (noise). Also note that when using a utility that reports signals as 4 or 5 bars, each bar represents 20-25% of signal strength. So one antenna may be pulling in the signal 15% better than the other, and yet the difference in bars may be only 0 or 1. We recommend using more detailed programs for precise signal strength analysis. Our support staff has over 100 years of combined Wi-Fi and antenna experience, so please contact us for help with antenna placement and details on what programs to use for signal strength testing.

How far away can I pick up signals with this compared to a standard antenna?
-For this question there is no exact answer. Wireless range is an imperfect science. The range you get with any adapter will vary markedly depending on the strength and quality of the wireless access point being used, as well as obstacles and interference in the area. Keep in mind that interference can often be invisible. This antenna is a directional antenna that should give you a better signal and longer range to a particular signal when it is pointed in that direction, vs. an omni directional antenna of the same game. Things such as antenna placement (even just a few feet) can have a big impact on performance. As always, if anything seems off about the product performance, please contact us directly for one on one assistance. If you are trying to pick up signals from far away, and are not sure this will give you enough range, please contact us with details about your situation and we may be able to offer an opinion.
