I live in the suburb of LA. I have 3-4 bars out side of my house with Verizon service, but because of my metal roof I have no service in side. I also work out my home office, so every time someone calls, I had to run out of the house to answer the phone.I took the advice of the PVC pipe about 8 feet above my roof, ran the cable and put the base unit in my attic. It worked like a champ on the first try. It didn't take long to install at all for a guy that is not very handy to begin with. Now I have 3-4 bars in my house and my wife's old school phone have 5 bars all the time.I highly recommend this product if you have similar problem as I have.
