TP-Link Omni-Directional Antenna

This things work great.  I lost my original antennas while moving and purchased these to get back up and running.  I'm so glad I spend a couple of extra bucks on these instead of just getting the ones that came with the card.  They work so much better...

Please improve the product by adding a circular directional indicator on the power supply base.  This might be accomplished by using 12-24 LED's that light in sequence upon adjusting the antenna's direction remotely.  The purpose would be so that the viewer can be aware of the direction of the antenna.  Certain channels have better reception associated with a particular direction of the antenna.  A directional indicator will help the viewer find the "sweet spot" more quickly.
Make it quick, I'm holding my breath.

Our PC that uses a D-link DWA-552 draft-'N' wireless card has its three antennas very close together and extends out the bottom rear of the PC where other PC Cables drape down onto or near them.  With the PC on the floor under a desk, the antennas are in a very poor location.

The "signal strength" would register between 50 and 60 percent from our router not really that far away (but with multiple walls, desk wood, and shelves inbetween).

Although the cable is only several feet long, using this device to move the antenna location away from the rear of the PC into a much better location a couple feet up a wall and a couple feet away from the PC resulted in constant signal strength of 100%.  This increased throughput between 2x and 3x from what it was before and would stay there a bit more consistently in it's fight against signals from the neighbor's networks (at least two others are in range).

The antenna itself is probably a little bit better than the PC card's in that the antennas are further apart, but this would likely not be an advantage when hooking to a router.

The antenna elements don't look like ones with additional gain (fairly short).  The big advantage that worked for us is the ability to move it into a better location/orientation -- and it being spread out a bit further than the PC Card alternative.  It's not an antenna that gets better range due to being directional.

For us it worked great.

These TP-LINK AV500 adapters are pretty good and compatible with my older AV200 adapters.

For maximum range, i recommend the newer AV1200 versions. They use all 3 wires for MIMO and beam forming to get better speeds and/or greater range.

Installed them at my sister's house where I had trouble receiving the wireless signal.
I have a computer in the garage which is about 100' from the wireless modem inside the house.
the TP-Link works great. No more dropped signals.  I even have it plugged into a multi outlet strip
with no problems.

This product matched with a 14db directional antenna worked well for bridging a building to another.  The interface is simple and straightforward enough that I had it setup in 5 minutes.  The only thing I would change is to give it more power.  I believe it's only around 14dbm transmit.  That being said, I had no problems using it with my configuration.

This antenna works very well ... just as advertised.  The delivery was prompt and the item arrived in excellent condition.  I will buy from this site again in the future.  Thanks,  YLA

Fantastic antenna. Used it for a TEW-623PI and works like a charm. Perfect signal all throughout my house.

Compact and very efficient antenna. Works well in both bands. Obviously works better than omni-directional dipole antenna. Quality made, like all other original stuff made by Alfa.

This little antenna does worlds of wonder when the phone is right next to it. It helps maintain a reliable signal, which is exactly what I need it for. I installed this on a window in my house and placed a T-Mobile LTE booster right next to it and boom, 5 bars; whereas previously with the T-Mobile LTE signal booster couldn't get a signal.

Great antenna! Make sure you look at a map of DTV stations so you know what direction to point it in (not omni directional)

I bougt this antenna to use with my Tivoli Audio One table top radio.  I am not an Electrical Engineer, and I was a bit skeptical that it would make a difference given that it is not physically wired to the radio.  When I opened the package I placed the antenna on top of the T1 and dialed in an AM station that seems to share bandwidth with another station, which creates bleed-over from the other station.  Once I dialed in the frequency on the radio to its clearest setting, I did the same with the antenna's tuner and was amaxed when the extraneous noise vanished.  I am very satisfied with this unit and carry it from one room to the next when I am listening to other radios in the house.  Great product, works as advertised, weighted base, even looks expensive but it isn't.

If I were physically able to mount this antenna up higher, I would be able to receive radio signals from anywhere!  Very well made.  Securely packaged.

Used with the vertical omnidirectional antenna to start with, in case one cell tower is down I can work through others. You need to read the instructions carefully and adjust the inside antennas and gain controls to prevent oscillation which would block out the cell signal you are trying to send and receive. I'm thinking perhaps some of the negative reviews did not do this. This is a very high gain bi-directional amplifier, it's a miracle of rf UHF design but needs to be adjusted so the amplifier lights are both green (one light per cell band). It's in the instructions but they really need to be read and  followed . With my iPhone I used to get 1-2 bars inside the house and could only make long conference calls from a few places. Now it's solid all across the house with the exception of the farthest reaches which never had any cell coverage possible. I'm planning to add a signal splitter to the amp and another indoor antenna back there as the instructions suggest. Very good performance with multiple cell phones and iPads including the fussy iPhone. Just switched my iPads to tmobile so signal was a bit lower but now it's full bars. Of course I use WiFi at home but sometimes the cable modem is down or clogged with too much Netflix.. BTW I use the Wilson cellular car amplifier and external antenna in the car and I finally have full coverage at home and on the road. I've used Wilson equipment for ages on 144mhz and always been happy with the quality of the product.

I live half-way between Dallas/Ft Worth and Waco, the tv stations I want to get. I was hesitant about an omnidirectional not getting a strong enough signal from the two almost polar opposite directions. I mounted it about 9 feet above my house and I get excellent HD reception from both directions, I am even getting an erratic signal from a station  much away further that I never expected to pick up. Item comes simply packaged, formed cardboard instead of styrofoam, very easy to install. I have it mounted on 3/4" conduit, does not overwhelm it with weight. Appears solidly constructed, support brackets are strong and ridgid. While I was not concerned about appearance, it is an unobtrusive unit that would not detract from the side of a house or eave.

I actually just got this TP-Link Adapter today. I am putting an older desktop into use that didn't have wireless.  Installed the drivers, plugged it in and BAM!  Internet with a stronger signal than anywhere else in my house.  I love the USB extension cable so the antenna can sit on my desk with the tower underneath.  Great product!  I highly recommend.

I needed a long range antenna to connect to a network about 1/8 mile away. It works great. When I first installed the antenna, I couldn't believe how many networks it found. It doesn't require any drivers with Windows 8. Just connect it to the USB and it works. It also comes with a WIFI utility program. I downloaded a later version on Cranes website for Windows 8. I also ordered the 30' extension so I can mount the antenna on the roof if needed. The antenna is Omni-directional so you do not have to worry about pointing it in a specific direction. Makes installation much easier.
