Customer Review: Poor description!
Recently purchased this product and did not know that it has an external antenna that needs to be installed somewhere outside of the apartment/house. Since my apartment is small i didn't know that the device needed an additional 15 feet distance from antenna to device. I was disappointed to find that i was not informed of this when i purchased the item.
Customer Review: works better than expected
My house is on the wrong side of a small hill in a wooded area and has no reliable cell phone coverage, and had unreliable coverage in a couple little lucky spots. I have a yagi antenna on the roof aimed toward the cell sites, lightning arrestor, and a 50' cable coming in from the attic going to the basement, and up to the first floor office. Here the Wireless Extender attaches. I went from nothing to 20-80 percent of the signal bars depending on where I am in the house. The cell phones now have good signal and function properly.
