For clear cell calls in my house I had to go to the front windows and stand there to talk. A friend mentioned Cell boosters and I was interested and started investigating. I went to [...] to see where the nearest cell towers are. I purchased the Wilson Electronics DT signal booster. I went to their website and downloaded the manual before the product arrived. Read the manual so I would have an exact understanding on how it works. I downloaded an app called phone reception monitor to my smartphone. You should not use the bars on your phone and even Wilson electronics tells you this. I have Virginmobile and my reception is 20-30% (using the app) in my house and 41-45% at my front house windows. I have aluminum siding on the house and this can affect cell signal. The Wilson Electronics product arrived and it came with 1 20ft reel and 1 30ft reel of RG6 coax cable, 1 cradle antenna, 1 booster, 1 Desktop antenna and assorted hardware and mounting brackets etc. To test I mounted the cradle antenna at my front window with the suction cups supplied, connected the 20ft and 30ft cable together (with the supplied connector) ran the wiring along the floor to the booster in another room, connected the desktop antenna and sat it on a high shelf about 6ft high and pointed it thru one room to a large den. Plugged in the booster, two green lights came on. Turned on smartphone and my signal at the Desktop antenna said 65%. WOW, I have never received such a signal. Walked about 35ft to the end of the back den large room and my signal dropped to 40%. This is the signal I would get at my front windows! So here is my first test. I went to the kitchen which is 20feet away from the desktop antenna and to the side of the antenna and called virgin mobile and the call was crystal clear. This is an area where I could not make a clear call before! Also my data increased as follows:
