1.0 Introduction
The ETS-Lindgren Model 5503 Series E&H Field Generator creates a vertical
or horizontal electric field. This two-conductor transmission line system consists
of parallel radiating elements attached to a non-conductive, non-metallic frame,
as well as a load and balun boxes that are mounted on the frame and attached to
the ground plane. The Model 5503 is available in three sizes: 2-meter, 3-meter,
and 5-meter.
The two operating modes of the field generator are:
• E-Mode (Common)— When the current on the two radiating elements
flows in the same direction, a vertical E-field is the dominant field
component. Field distribution simulates that of a quasi-static
parallel-plate transverse electromagnetic mode (TEM).
• H-Mode (Differential)— When the current on the two radiating
elements flows in the opposite direction, a vertical H-field or a
horizontally polarized E-field is the dominant field component. Field
distribution is approximately that of a quasi-static two-wire transmission
line. A balun is used to isolate the elements from the ground plane.
The Model 5503-2M and Model 5503-3M include two plug-in low power
balun boxes, one for E-field operation and one for H-field operation. The
Model 5503-5M includes one high power balun box for either E-field operation or
H-field operation.
