Money Well Spent!

I have tried so many gimmicks over the years, trying to make my tv picture clearer, trying to do this or that. Most of the things I have tried seemed to make sense at the moment when I ordered them but when you get it and apply it and it does either nothing at all or even makes things worse. That is kind of what I was expecting from these Alfa antenna. I have looking around at new ac routers (I have an Asus rtn66-u now). My Asus router is a great router but I thought maybe a new ac router would be able to blow it away. I had recently gotten a speed increase from Comcast and it was very evident when using the wired part of the router but my wireless was nowhere near where I thought it should be. As a last resort (because I have tried just about every other thing that was doable. I did several speednet tests downstairs(router is upstairs and other side of the house) on my wife's laptop and was pulling 35Mbs-39Mbs on 5.0 radio band. Then I screwed on the new Alfa paddle-like antenna, adjusted their positions logically and prepared for a minor if any increase. The first was 95Mbs and after a little more fine tuning it is now putting out 135Mbs. I know this review is way long and I apologize but this kind of got me excited. For me this was a huge increase and I love it (only bummer part of this is it kind of blows my justification to my wife for the need of a new router out of the water. Great Product Alfa.

Updated Great Antennas over stock options.

Update (3/5/16) Turns out that my problem was the adapter and not the antennas. After trying with a new adapter, these out performed to two stock antennas. It may take a little bit of work to find the sweet spot on these (they have a 66 degree horizontal and 16 degree vertical signal arc) but they do provide better signal reception. Bought this as a suggesting to help with issues I was having with the Alfa AWUS036ACH in terms of maintaining a stable connection. After using these, I ended up going back to the stock antennas as the performance with these were even worse. I had had luck with using directional antennas before with other products but after testing these with multiple adapters, the stock antennas outperformed them every time.

It works!

I purchased two of these. Added one to my netbook with a USB 5.0Ghz adapter, I this use to connect to a Xfinity Hotspot at work. Using a free wifi signal analyser app I was able to improve the signal between 10-20%. This also allows me to stream from the Xfinity TV webapp. Internet speed test show a constant 20-25 Mbps. The second I added to my ASUS PCE-AC68 on my main PC, My download speed increased by 40 Mbps. I use this PC to as my media server and now have eliminated my buffer issues over wifi.

Alfa directional antenna in window sill improved wireless signal

LAN connectivity was erratic to my shop 100 feet away from the wireless router. Changed to an ASUS PCE-N15 wireless card and the Alpha APA-M25 directional antenna with a 4 foot antenna extension so the antenna can sit on the window sill. Now wireless signal is solid with no loss of signal. I am delighted with this antenna. The wireless card has two antenna connectors, so I had to find which one worked best. Presume that is the 2.4 GHz input because of distance. This antenna saved me from going to a much more expensive solution.

It's a remarkable difference coming from an omnidirectional antenna

After installing it (of course, it's pretty easy: unscrewed the previous omni antenna and replaced with this one) and aiming it correctly to the device with bad connectivity, the speed is 5x what it was before. I wasn't expecting such an amazing improvement. It is worth repeating something: if you don't aim the antenna correctly, is not going to work. Is a DIRECTIONAL antenna, that's the entire point.

Great addition to my DJI Phantom 3 drone transmitter. Distance out to 3,500+ feet.

Great addition to my DJI Phantom 3 drone transmitter. My distance went from a few hundred feet to over 3,500 feet with the addition of the Alfa antennas. You need to make some slight modifications to your transmitter by adding port for the antenna. Overall it was a nice addition to my DJI Phantom 3 transmitter.

Great for Netgear ac1900

Attached this to my Netgear Nighthawk r700 ac 1900 router and pointed it to my Rosewill RNX-AC1900PCE, 802.11AC Dual Band pci card upstairs two rooms over. I was able to get a solid connection when before I could only get 1-2 bars. This solved all my wireless issues in a very simple no hassle way, literally just screwed this onto my router.

Going through a floor I went from a best of 130mbs to 230+mbs

I would rate this from 1 stars to 5 stars depending on how you use it and what you need. I first attached it to my expensive 3 antenna asus router replacing one antenna. As another reviewer said it won't rotate properly to face backwards. Internally there is a stop so it only rotates 180 with the 90degree flex. I laid down my router which would lessen it's cooling and looked odd and unstable to test it. Measuring data rate and cell app signal there was no improvement. 1 star. I then attached it to my receiving usb dual antenna dongle wtih stand with a RTL8812AU chipset that I purchased on amazon. I have trouble with it coming back from sleep or hibernate with win10 and have to reboot daily so I won't push you to a particular url for that. Replacing one of the antenna's on it and experimenting with free internet speed tests I was able to make big gains in mbs. Going through a floor I went from a best of 130mbs to 230+mbs ! This is my max ISP speed on my paid plan with the 5ghz channel, the 2.4ghz channel slow starts and 70mbs best. I should mention this is replacing one of the already high gain straight antennas made this much difference.

Before they had -75 and after they received -70 If they added a directional antenna on the repeater as well they might get a muc

It does work I tried it with a wifi analyzer. Dont think its going to help alot because it wont. It just takes the wifi and helps focus the signal in one direction and adds a very small boost. I had -48 before and with this unit I got -42, that 6db gain is a lot when your on the boarder. After I did some test I aimed it out the window to my friends house and they picked up the signal with a wifi repeater. Before they had -75 and after they received -70 If they added a directional antenna on the repeater as well they might get a much better level, maybe -62 to -65.

Exceeded my expectations

This little guy really will concentrate you signal into one direction. Extended the wifi range in that direction but about 50 feet, enough to include a cabin about 100 feet from the main house. 5G boost is significantly improved over 2G. Pairing one antenna on the router with a second on a USB WiFi receiver or Range extender with removeaamble antennas was far superior in terms of throughput and range.
