Having your outdoor antenna above a metal roof leads to another thing. All gain antennas radiate in what we call a beam. Any antenna at a reasonable height forms a beam that is slightly aimed upward. This is not good. A sloping metal roof under the antenna will tend to lower this beam more toward the horizon. "Tend" is the operative word here. The help is not perfect. $1 to 2K / install...I am in the wrong business!!!

If you own you know, if you rent you will need to check. > Yes, and actually, having the metal roofing between your indoor antenna and the outdoor antenna is a good thing. this is one of the things I struggled with, finding a location where the two antennas did not interfere with each other. i spent a whole day doing this last fall. That said, the person talking about a pro install costing 1k or 2 sounds reasonable! One more thought: the device someone mentioned that converts your cell to use a hardwired internet connection from verizon sounds like a good, easy, relatively affordable choice. but i wanted something as a backup to my internet as we also use VoIP, so if internet goes down we have problems. With backup cell service at least i could tether if needed. -- Thank you, Matt Lampiasi Florence I.T. - A Community IT shop. 413-303-9167 or @ florenceit.net <http://florenceit.net> Join me on twitter <http://twitter.com/florenceit>.
