I actually bought two of these.

The antennae on the top and bottom (or zenith and nadir) both snapped off before I completed it the first time.  Removing some of the smaller pieces from the sheet would cause bandage which would lead to breakage.  Pieces that need to be bent at right angles have a limited amount of bends they can take before they snap off entirely.  And one seems to have no choice to bend some of the pieces to a certain extent when removing them (based on where and how they're connected), but that extent is too much for certain pieces to remain in one piece.

I bought it a second time because the price was right, and I wanted my Hubble to have antennae!  That time I was extremely cautious, following a mantra that said to be gentle and patient, to take as much time as a piece needs to be removed, and to not force anything.

Pssshhhh. (See first paragraph)

This is a decent antenna.  I have not actually measured the antenna gain, or input impedance, or radiation pattern and I am not going to .  Plugging my WIFI router into boosted the signal enough to max the bars on my phone anywhere in my house.  I am using it for both 5.8GHz and 2.4GHz and the signal looks good on both.  This is a good antenna to use if you are going to put it at one end of yr house.  Good directionality.  I have been an antenna design engineer in the past and I don't think I could have designed a better one very quicker easier or cheaper.

I only needed one antenna, but for that price it's good to have some replacements (just in case). No issue, only screw to the wireless card terminal, and that's all! If one has the ethernet cable set as the default connection, you must open the conexions center (clicking at the task bar) and set the wireless option. Also you may need the wep key or password of your router, write it and click "connect", now the little bars icon must be full, indicating an excellent connection.

It is a great antennae....the velcro is plenty strong and it has an extra set of velcro tabs to keep the antennae in place.

I have had one of these over 15 years. I thought mine had died on the weather channel so I bought another. Lo and behold it was a radio tower  issue . Now I have two.

Got this antenna from my uncle.  He bought two of these from one of those stores that sells things for cheap for $20 a piece.  This antenna is cheaply made, very delicate, instructions for assembly are horrible and the rotation motor is very finicky.  That being said, I put this on about a 16-20 ft pole which fit inside an old DISH satellite pole already in place.  My dad and I "engineered" it to fit to the top of the pole and pointed it toward where most of our channels come from (Birmingham).  It picks up better than I could have imagined.  I live between Montgomery and Birmingham but have it pointed to the degrees for transmitters found online.  Not only do I pick up the Birmingham channels but I pick up Gadsden stations also.  I also pick up a few Montgomery stations and one of them is 80 miles away.  The only problem I have is that I cannot pick up PBS (APT) and it's in the direction and close to the other Birmingham transmitters that I have it pointed to.  Usually I've been able to get PBS out of Birmingham and/or Mt. Cheha.  Strange that I can pick up everything I watch, plus some, but not pick up PBS.  Reasons for 4 stars is that it may not be for everyone because it's a pain to assemble.  You basically have to look at the picture on the box and not the instructions. You have to be careful because the parts are thin aluminum and could be bent easily.  The kicker is that I can't get PBS.  Other than that, it's a great antenna if you don't have to use the rotator much and can safely put it together.  I'd recommend as high as possible in an area with not many trees.  Mine is about 16 - 20 ft. up with a few trees in the way.  As far as it lasting in the elements, it has proven to withstand gusts and sheets of rain from bad thunderstorms and the remnants of Hurricane Irma that came by here.  It swayed a little but I never lost reception.  It's so light at the top of the pole that it would take unusually high winds to take it down.  If something hits it though (tree limb), it's done for because it's a $20 antenna.  Thinking about getting this for my grandmother now so she can cut out satellite.  The only stations that she watches I can get OTA with this antenna. My uncle is happy with his also.  His is about 12 ft. up.  The photos are of my antenna.  First one looking north toward Birmingham with tree obstruction, the second is looking south toward Montgomery, Alabama.

After getting 2 of these that did not work I'm happy with the one I have now. I am concerned whether it will last based on getting 2 in a row that would not work. The first one the transmitter would not come on at all. The 2nd one worked intermittently. It has a very good range and works as advertised. Maybe I just had the misfortune of getting the only 2 bad ones.

Picked up two of these yesterday and I'm very happy with them.

They have one great feature in particular - through the menu you can access a signal strength meter.  With the meter on, you can adjust your antenna for the best reception and it tells you the strength as you make adjustments.  It takes the guess work out of it!

I have a dvd player with a built in converter on one of our tvs.  I temporarily plugged in one of these boxes just to find the best antenna position and now we get several more channels.

The only thing I don't like is the remote.  But I plan on programming a universal remote to work the box so I never have to look at their ugly one again.

I want to love it but this is the second time I've had to send it to the manufacture to replace the antennas on the device! If you move your PC around like I do just be careful and remove the antennas before you work on your computer.

I read the other review and apparently that customer did not hang the square antenna in the window. It works very well if you put the antenna in the window, which is the other option. It comes with suction cups to use to hang it on the window. I also bought the extension cord and booster that plugs in. Works great. I am thinking of buying a second one.

I like that it actually works!  I'm receiving the same number of channels as I did with a $60 antenna, which I returened.

When I first got this and hooked it up it didn't really work that well. Then I sat down and read the manual and now understand how critical antennae placement is. Followed the recommendations and now it works great. I went from almost nothing, to five bars back in my bedroom.
I have noticed that it does lose signal for a few seconds randomly while I'm on a call. It doesn't drop the call completely, there's just a brief second when I can't hear anything. I think it might be the unit's signal competing with the actual signal from outside.

Normally, I wouldn't buy these, but the antenna connector on the MBR1200 is some odd connector I've never seen for wifi antenna's so I purchased these which are made for the MBR1200. They do increase the range significantly, and the connection is still strong when I'm out 800-900 feet and the signal strength is down to a single bar on my iPod.

I live 25 miles away from the nearest Free to air Antenna and catch the channels some days only and next day I get other channels, I did buy this one to replace another one that was broke but  the old one is even better perhaps is broke in a cople of wings, I have other antenna in the same pole for other two TV's and I do catch lots of channels, is called Xium Air, I did try to buy one more but the company is out of bussines

I  only listen to two stations.  One is strong.  One is weak.  After I replaced my broken antenna, I was able to get the weak station again.  It seems to be comparable to the original antenna.

It works for me, but just barely. I am using it in my office. My office does not have an outside wall, and I was getting zero to 1 bars without it. When I first installed this, I was able to find a location next to the ceiling where I had two bars consistently. I located the window unit there, but even though my phone showed 2 or 3 bars, my calls broke up severely.
  A few days ago, I put the window unit above the ceiling, where I had three bars, and it started working. However, the only way it works is if I leave my phone sitting next to the antenna, and use my bluetooth. If I move my phone as little as 6" away I go to 0-1 bars. Any farther and I have no bars.
  My other big problem is that if the antenna is too close to the window unit, there is a back feed, and it stops working. That wouldn't be a huge problem, except the wire isn't all that long, and once you run it down the wall, and across the room, it is nearly impossible for it not to pick up the antenna and it stops working. Since installing it in the ceiling this problem went away, but I can no longer run the wire all the way to the floor and over to my desk. It looks pretty bad, and it may cause me problems with my boss. I wish I could add another 12-20 feet so I can install it neatly.
  Bottom line. If you don't have at least 3 bars where you locate the window unit, and you can't leave your phone sitting next to the antenna, then I would recommend you stay away from this item. One other comment is that I think it should be designed to work the other way around. The black antenna should mount on the window and the main unit should be located near the phone. Running both power and the antenna wire into the ceiling or to a window is just plain stupid. But, for $50 it is working for me, and I'm happier than I was.

I have one of these and it used to work a little, now it ain't hitting on doodly squat. I have it up in the air on a mast, connected with LMR 200 and all, nothing, ZERO- ZILCH. Here's the killer of it all right here, I can walk out the back door with the Modem and its short omni directional antenna and get 2-3 bars, mostly 1 & 2. So I need just an omni directional outdoor antenna to finish this once and for all. ANd no I do Not Want to spend another $300 getting it done.
