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,
