Absorption. Conductive material such as steel, metallic pipe and siding, and tree leaves
and branches absorb more of a radio signal than concrete, bricks, sheetrock, plastic, and
wood. Due to absorption, you may have shorter readability distances in industrial or
business areas than in residential areas.
Shielding. When conductive materials are close together, as in metal partitions or
narrow-mesh fencing, they act as a shield and absorb the entire radio signal. Move a
short distance away from conductive material so the ERT signal is not shielded. Keep
moving to assist in receiving signals that may be shielded. Metalized fabrics should not
be worn over the radio as they may severely reduce reading success.
Reflection. Radio signals can be reflected by some of the same types of conductive
material that absorb them. Move a short distance away from the reflective material to find
the direct ERT signal or a strong reflected signal. Keep moving to assist in receiving
signals that may be reflected.
