This paper tests the radiation compliance of a GSM base station antenna located in a rural area in Greece. The installation in consisted of a single antenna mast and is build on a hill. In this paper there will be an analysis of the actual measurements taken on that site, as well as theoretical references regarding the calculations of the electromagnetic field. We will also review the RF safety reference levels adopted by the Greek national law and compare those levels with the actual measurements. By doing that we will clearly deduce that the measurements taken were well bellow the given standards.
