I live in a French farmhouse with very thick stone walls. As a result, the SFR 3G signal strength inside the house was zero or one bar only, -100dBm to -109dBm. Data speeds were terrible. I also had a very slow fixed broadband speed of 0.5Mbps or less.
I was searching on the internet for a 3G signal amplifier and found the MyAmplifiers website. I used the live web chat helpline and got immediate advice on which amplifier I needed. I ordered the Any Tone AT4000W which arrived within a few days. While this amplifier certainly worked, unfortunately, it was not powerful enough for the size of my house. Coverage was not good enough to improve the network signal throughout the house.
So I contacted Julia in MyAmplifiers Sales Team and she recommended the Any Tone AT6100 3G which she offered at a discount. So I returned the AT4000W and ordered the AT6100 3G instead. It also arrived quickly.
The AT6100 3G is fantastic. The coverage area is 500 sq m and it provides 3 or 4 bar coverage in every room of my house. It worked immediately, and all devices in the house benefited from the super strong signal.
I would also add that the cables provided to connect the external antenna to the amplifier and then the amplifier to the internal antenna are thick and black and so are not so pretty in the house!! Hard to hide them, but it depends on where you can install the amplifier. Also, it is necessary to somehow make a large hole from the inside of your house to the outside to pass the cable through. This is not easy depending on your situation.
I highly recommend MyAmplifiers and if you choose the right amplifier they really do make a huge difference. I now have -85 dBm signal strength and internet speed of 4 to 5Mbps!! Fantastic!!
