Thought I would start here for this question. I would like to build a
passive antenna for my cell phone that has no port. I know it goes
into the 1100 MHZ range if that helps. I would like to use this for
using in my house and for car use. Unless you know of a good link to a
site that sells such a thing. It seems like every new cell phone I get
over the years never has the range that is needed to pick up the towers
in my home (upstairs) or in my car over country roads (drops calls).

Thanks
