Cell Phone Antenna - External Passive Repeater Antenna

The people who are posting negative reviews on this product must obviously be installing it in the wrong location or something!!!I drive around a 300 mile route each working day and had all the dead zones memorized... after installing this antenna this morning my signal only dropped out and became temporarily unusable one time on my entire route. I was shocked at the difference this thing made.I drive a Nissan NV200 and installed it top center windshield with my phone cradled about 2-3 ft. directly below.(Absolutely amazed here...using T-Mobile in Tulsa and surrounding areas... will update if anything changes.

I received the passive repeater antenna, tried it out and could see no difference in the cell phone signal strength (bars) in my house than before. I then wrapped it in aluminum foil to isolate it from any radio signals, and no change was discernible. I conclude that this device does nothing, and it is too cheap to bother trying to return it. Caveat emptor!

No signal difference

I had no expectations from this due to reviews and price. I have in and out cell service at my house with my new provider and phone calls get dropped 95% of the time.. I bought this and at first, when I put it up, there was no change. But when I checked later, I had 3g(which was never there before) and I had 3 or 4 bars. I haven't dropped any calls as of yet but I do notice fluctuation in the bars BUT nothing like I had where before this antenna. Was it worth it for me? Yes. I can't afford to spend $$$ on other systems. This was easy and simple...another plus. I do think you need to have at least a fluctuating signal or it might not work with no bars or 1 bar. Not sure.

Not as good as I wished. However, it did raise my mom's signal by two bars on a good day, just ONE most days. But without this device the signal came and went routinely in her rural mobile home.

For me it seems to works ok. Sure I may not get 4 bars of service, but I may get 1 or 2 bars. I have one on my car and 2 located around the house. Their easy to install no tool required. You have to clean the area your going to put it very well so it will be able to sick.

Do not work at all. Waste of money.

I have 2 out 5 bars now. So no drop calls.
