Boosts signals of OTA channels
582276
My father in law uses this to boost their signal coming from the antenna on top of their house to all TVs in the house. With it they get more channels and better signals than without. This is the second one of these we had to buy - the first one broke during a power outage - which is fine - electronics will do that sometimes but the thing is - when this happened it broke in such a way where it no longer had power ---> and was actually degrading the signal causing less channels to come in. So be on the lookout for that and maybe put it behind a surge suppressor .... anyway when it is working it works well!

Got this to replace the failing amplifier on our old Terk indoor antenna, and it does indeed bring our OTA (over the air) TV signal back to the same level as when the Term amp worked well, there would be more gain on an outside antenna.  The adjustable gain does increase or decrease the signal by 7 to 10 db but only on our clearest signals.  On the plus side, the unit seems to be fairly sturdy and well made, comes with pretty good instructions, and was easy to install, and gives a decided boost to the digital signal.  Our digital decoder box signal meter runs from 0 to 100, with a signal in the low 30's necessary for decent viewing.  This  amp boosts  some stations reading in the mid 20's into the low 30's, but I expect to see better performance in the winter when the leaves are gone.  It won't work miracles, but if you need a modest boost in signal strength it's worth the modest price.
  (Warning: RANT: This digital signal stuff stinks.  With analog, we were able to get decent to great signals from towers in three different directions at distances of 20 to 60 miles with the Terk.  Analog signals were affected by weather and time of day but not nearly to the extent of these digital signals.  Now, we can count on losing signal when the trees leaf out, blackbirds flock, rain, sun, mist, clouds, no clouds , traffic jams on the Blue Ridge parkway and for all I know someone on the fourth floor of a building moving their ficus tree onto the balcony in the path of the digital signal. End rant.  Excuse me.)

The amplifier does increase the signal strength based on what my sony TV indicates. I now got few more channels than my Philips flat indoor antenna. Although looks very big, its flat and light weight design makes it easy to be taped on any surface.

Will provide longer range and better clarity than the stock Baofeng antennae. Worth the added cost for a better signal.

This is an amazing product. You can see the boost on the signal strength.

It definitely boosted the signal, but not as far as I would have expected for the advertised 8w. I got about 1-200 feet direct line of sight.

Works nicely, as advertised.  I had previously tried two other foreign made brands of boosters that wouldn't even pick up the signal from the tower.
I purchased this booster over two months ago to improve the cellular signal inside my barndominium, a home where the outer siding is all metal, which literally kills cell phone signals. This booster beefed up the db strength from the cell tower and resulted in boosting my cellular signal from one bar to a solid five bars inside my home.
The booster tends to run a bit warm and I was concerned about its longevity, but so far, not a problem.
Set up is easy:
First, install a cell tower signal finding app on your cell phone.  I used the OpenSignal app recommended by weBoost.
Climb onto your roof or wherever you plan to mount your exterior antenna.
Using the OpenSignal app or a comparable app, find the cell tower that gives you the strongest db reading.  Look for the dBm (db) reading strength, NOT the number of bars on your phone.  The db reading tells the real story.  The lower the db number the stronger your signal is.
Example:  -60 dBm is almost perfect.  -112 dBm and you will suffer dropped calls.
 You may be surprised to find that there are a number of towers in your area.  Mount your external antenna and point it in the direction of the tower emitting the strongest signal.
Run your cable from the external antenna to the input of your booster at your chosen mounting location inside your home.
Run a cable from the output of your booster to your indoor antenna which should be located in an area that exposes it to the largest desired area for signal reception.
Apply power to the booster and you should see the four green Leds on the booster light up.
Job Done.

I installed this antennae next to my chimney. I received all channels clearly except channel 9 which the signal breaks up occasionally. I give this a thumbs up. I will try another amplifier to see if the signal improves.

Fantastic - a huge improvement (in the same room) over other indoor antennas; am getting pretty much all available OTA channels in my area. The design also allows it to be hidden which is a bug plus. I wish I had invested in this earler - very much satisfied.

I live in the mountains where my signal is very low. After installing this product which was very simple. I now have almost a full signal on my phone. It has also helped improve my signal on my wireless satelite modem. its a great product. I would recommend it to anyone needing to boost thier signal.

This antenna is useful for improving coverage in a 120 degree angle from from the active side. While the gain is only equal or 1-3 dBi improvement over a typical rubber ducky omni that comes with many devices, the improved signal to noise ratio can result in much better connections in congested locations.. which these days is just about anywhere.

The construction is well made for a consumer device but I did find that it rotates too easily.. I used a piece of tape to lock it in position. .. not a big issue

Of course, first check out the connections of your device.. the previous numb-nut reviewer bought this for a device with fixed antennas!

Wow these boosted the signal by double. i use them on my PC on the second floor. and it went from 1 bar to 3!

These little antennas are great!!  They are a snap to put on, and really increased the signal.  Best way to increase wireless signal.  Install a higher gain antenna.

Gives good signal in areas of house that were previously poor

replaced an inferior quality product and resulted in better reception for a TV using a home made antenna for use with OTA broadcast signals.

I was able to get OTA TV stations on my Directv box with the help of this amplifier (I can actually get more stations than Directv will let me access through their guide, but at least I can get the ones I really want.

This combiner allows to take signals from two HDTV antennas and combine them before connecting them to a signal amplifier. It definitely makes an improvement you can see with higher signal strength at the TV. It works for me so I'm glad I got it.
