-10db gain (4G LTE) when installed on the roof with the tower 2.7 miles away; speeds dramatically increased. This product does exactly what it says it does, is a fair price, and purchasing from 5Gstore is the icing on the cake.
Above this was the 'long story short' version, here's the more in-depth version: We live out in the middle of nowhere in a complete dead zone. If you look at a map of cell phone towers in the area they form a circle around our house so we don't get good signal with any carrier. After working with 5Gstore in the past for my dad's home internet I went to them again for my mom's place. We got an aircard from Verizon; this antenna, and the low loss cable from 3G store. 3G store's shipping was prompt, the items were well packaged, and customer supper was great as usual.
We mounted this antenna on the roof pointing in the general direction of the closest Verizon tower and called it good. Plugging the antenna in brings the signal from -104 to -94; a great improvement! Speed test results show faster pings (50-65ms from 70-120ms), increased download speeds (3-5Mb/s from 1Mb/s), MUCH faster upload speeds (7-9Mb/s from 1Mb/s), and the internet is much more consistent.
