Car Cellular Phone Signal Booster & Repeater Antenna 5G, 4G LTE for Verizon At&t Sprint T-Mobile Phones by Cellet

We put them on our deer blind window. Got at least one bar more of signal. One blind had no service and we had enough signal that I could play a movie. I bought two more for our other blinds.

Does nothing, setup is easy, but that tends to be true with snake oil products.

I got this to use in my camper. It actually works... a little. I use it for hotspotting so this might not work you. Put the antenna on a window, couple of inches away from the sides. You want to put the inside part directly over the antenna base. Then, place your phone so that it's touching the phone. I was able to slide a window up to hold it. It is important to have the phone touching the pad. That's it, and from testing signal strength my signal went from -110db up to 105db. Nothing tremendous, but a little gain from having a larger, outside antenna. This may help your signal inside rooms with a window, or in my case inside a camper, but you must leave you phone next to it.

OK, so I got to test this thing out today which is the 28th and even though it’s cheap don’t waste your money. This thing is a piece of trash and I’m gonna change. They’re just freaking pulling in your chain so don’t order it. It was just a hillside see I got my antenna and look right across the way on top of the hill. There is a cell tower and guess what this thing doesn’t catch🤔 signals.

I built a cargo camper and installed a single small window - absolutely no signal on my cell phone, no bars. I attached this on the window and now I can get a single bar when I’m close to the window and can make phone calls.

Before I installed this repeater antenna on my vehicle, I placed the two parts together and put a small piece of tape to hold them together, as they would be on a rear glass or window . Then placed them in a vertical position as they would be installed. So I could try different locations for an optimal signal. I found no increase in signal strength in any position. In my drive way my samsung a54 toggles between 2 bars 4g lte and one bar 5g. I had no increase in speed of apps loading incoming information, calls still fade in and out.

Picture for reference (and giggles). It’s attached to my pocket via magnets (thanks for the idea, I stole it) ;] Yes, it definitely works. I had to buy one because I’m taking college classes online and the signal in my area at work is sometimes shoddy. Also needed it because certain parts of the property have super weak signal. I sometimes need to use my phone for work. Awkward to send pictures and wait 10mins. Not anymore lol! 5’6ft for reference, no banana for scale. The bars don’t seem to change on your phone but sometimes it boosts up a bar. The real difference you CAN see is how fast it loads. In case you need to know, this is an antenna, NOT a hotspot replacement. Think of it like a fishing pole catching a data fish. Its long body helps pass that signal on. It doesn’t create a fish out of nothing. Great value. Honestly, I bought 1.5 inch sticky magnets, the magnet didn’t stick and ended up peaking off the seal and sticking them to the correct magnets. The sticky part holds so well. No gunk residue.

Doesn't really work. I haven't noticed a difference in signal strength. Easy to set up, but won't buy again.
