A cost effective and convenient system for converting a wireless phone that radiates stray RF energy outside of the intended RF transmission path into a wireless phone that confines the RF energy to a shielded RF transmission path. This system will be referred to as "plumbing" a phone. In the plumbing system, a shielded RF adapter contacts the RF output from the printed circuit board (the RF clip in certain embodiments) of the wireless phone. In certain embodiments where the wireless phone is prepared for various tests and/or performance measurements, the plumbing process involves a shielded RF adapter and/or some of the following steps: removing the supplied antenna from the wireless phone, modifying the antenna base if necessary to accommodate the shielded RF adapter, applying a conductive coating on the inside of the phone case to increase RF shielding and installing the shielded RF adapter into the antenna base such that the RF clip of the phone directly contacts an extended center pin of the shielded RF adapter. The shielded RF adapter and the plumbing system provide a shielded RF transmission path having a higher integrity in terms of mechanical strength and electrical performance than previous systems. Additionally, the plumbing system does not require any permanent modification of the printed circuit board of the wireless phone and does not require the use of an expensive shielded box in performing optimization tests. Thus, the plumbing system according to the principles of the present invention reduces the time, costs and resources for providing a wireless phone that confines its RF energy to a shielded RF transmission path.
