2.4HGz 7dBi RP-SMA Panel Screw-On Swivel Antenna for Alfa Netwrok Adaptors - Also Works for 3DR Solo Drone, DJI Phantom 3 Drone, Yuneec Typhoon H ST16 Controller, adds Range

Replaced only one antenna on a Netgear n300 wifi extender (WN3000RP) with this Alpha panel antenna. Works well. Now the extender concentrates signal in one direction for longer range pickup, and also has an omni antenna for local wifi connection. The Netgear is being used to pick up an Optimum hot spot 1 mile away (sparse housing, mostly woods) and distribute it in the house. Without the Alfa antenna, disconnects were so frequent that the link didn't work for more than 15 minutes, but now can stream Netflix for an entire movie with no problem. Without this antenna, the Netgear extender always displayed a fair or weak signal (orange or red LED) but now always shows a strong signal (green led). It appears that the side with the word "Alfa" is the send/receive side. This antenna is very popular with RC airplane and helicopter enthusiasts and they always mount it on their controllers with the lettering facing the airplane. Note: Modifications to the Netgear extender were needed to install an RP-SMA pigtail connector because it does not come with removable antennas. Update: Tested this on my desktop PC with a internal WIFI card by Gigabyte. The router in the next room, about 40 feet away with a wall full of bookcases in between. Connecting only to the 2.4Ghz router signal, using two 6dBi dipole dual band antennas, the signal strength was 66% and -60dBm with a speed test average of 70/35 Mbps down/up on a 100/35Mbps internet service. REPLACING ONLY ONE of the two dipole antennas with the Alpha antenna (I only have one) and facing the side with the "ALFA" print facing the router, the signal strength registers 99%, -40dBm with a speed test average of 78/35Mbps. So as you can see, there is over a 10% increase in download speed and the signal strength has increased by 50% and -20 dBi. Amazing for only using one antenna. Tests with the antenna facing backwards (text away from router) showed a drop in performance. There is some back side leakage, so the farther away from the router the antenna is, the more pronounced the effect of using it backwards will be. Compare those 2.4Ghz tests with using the same two dual band 6Dbi dipole antennas on the 5Ghz band and the speed tests are 115Mbps down, 35 to 40 Mbps up. To do your own testing, download freeware program "vistumbler" by Andrew Calcutt. It will list all wifi's in the area and their % and dBm ratings, as well as the mac addy, channel, authentication, and encryption. Very useful for testing antennas. As you can see,

There isnt many reviews here of people using it for internet. Mostly for drones. I wasnt expecting much, and honestly didnt care less that it was a 7dbi as opposed to a snub stock antennae thats 4-5 dbi. I wanted directional antennae and it certainly is. I am betting that 90% of the 2 stars and under dont understand how directional works. My transmission bout is about 200 feet away from where I wanted this to work. I was receiving a -60 dbi signal with the stock antennae. Workable, but not great and more or less just wanted to filter out interference (hence the directional). Plugging it right in and just ball parking the pointing I connected at -56 dbi. Ok cool, that boost comes from it being a direction and it being slightly stronger. Now I knew it worked so I pointed it a little bit more accurately and settled on -54 dbi. Now dbi works strangely, and you can read all about it other places lol. But short hand version it was a 2-3 dbi upgrade from my old antennae and I got a gain of 6 dbi on signal. That means its exactly what it says it is, a 7dbi antenna. It takes a bit of messing with pointing it for most applications, but it does exactly what it says it does....even the claim of up to 150% signal strength (I laughed at this but low and behold actually got it). The pics ive uploaded is a monitoring utility I use. My network is netgear83. Before and after shots. Youll also notice the list of networks has changed, confirming it is indeed directional.

For the money I didn't expect it to work at all, but surprisingly it really does [**see update below**]. It seems to boost signal in all directions better than my current stock antenna on wireless N router. But it does send the signal a little farther in the direction it is supposed to also. I was just surprised at how much it overall boosts the signal (verified my intuition using a signal strength app on my tablet) in all directions. In particular it was great for sending the signal up to the 2nd floor that previously didn't have many bars. My original plan was to keep one of the stock antennas on to give a donut-shaped coverage along the first floor, and then use this directional one to send the signal to the corner of the 2nd floor that had little signal strength. But after seeing how much it boosted signal seemingly all around (and not exclusively in the primary direction), I bought a second one and then REALLY noticed the improvement throughout the entire house. So overall, it does seem to boost the signal from my stock antennas noticeably. It does so primarily in the direction it is pointed, but much more all around also than I was expecting. For reference, I have a wireless N modem/router that is licensed to one of the major ISP's (that I believe is manufactured by Actiontec). *****UPDATE*****It did wonders for my home wireless N router, but when I brought them to a family member's house (and they have a much better $200 ASUS AC68U wireless AC router than I have) and tried installing this booster on two of their three antennae to fix a weak zone in the corner of their house. To my great surprise, these boosters did nothing for it. Literally nothing. The signal strength varied slightly like normal but I could not see any significant difference between the stock antennae and these boosters. It wasn't any worse either, but did not appear to boost the signal at all. This leads me to believe that these antenna boosters are really only good if you have a weaker router with lower dBi gain antennae on it. If you already have a nice router with very high-gain antennae to begin with, these boosters may or may not help direct the signal to areas you want. I lowered the rating to 4 stars, since it still helped greatly with my particular router, but be forewarned that it may not solve your problem if you have a very good router. And unfortunately I don't know the gain of the ASUS antennae to compare it to. There is a similar looking ASUS product to this one (that costs much more) that users have reported boosting signal for their more expensive routers.

The quality of this item is great, Used it to improve the range of my Wi-Fi and works better than I have thought it would!! Not only does it improve range of Wi-Fi but also improves speed and ping times in most online games. Price I was not happy about but after use of these antenna was glad I paid the cost of item!

No queda claro que el precio es de UNA antena ya que en las fotos aparecen dos. Y después no la pude cambiar.

do not like the results of this antenna ...only good for indoor use not for the long range i figured..my fault for not doing my research first..impulse buy....good enough for my modded ps3 didn't wanna run cable so i use this antenna to communicate with my wifi modem two rooms over.

Great little antenna, I used it with a USB wifi card to replace the omnidirectional antenna it came with. My card is now able to get signal through 2 walls and from the building 30 feet away.

OK product. I needed replacement antenna for my Asus router. They work fine. I wouldn't call them an upgrade. Shipped from China which took an extremely long time. If I had to do it all over again I'd buy a different product that ships faster.
