The purpose of the Test Article Support Column is to support the equipment under test securely, while at the same time having as little influence on the measurements as possible. The ideal support column would have a relative dielectric constant of 1.0, but supporting equipment on a column of air has proven challenging.

Test Article Support Columns are designed to have the lowest dielectric constant possible while at the same time supporting the load of the equipment under test.

The test article is supported on a block of low density polystyrene foam. This top cap is in turn supported by a thin wall fiberglass tube.

The standard support columns are identical for each of the different model wireless test labs except that the height varies to place the test article at the center of the test zone. The standard support columns are designed to support the load of a phantom head, phantom hand and handset.

Custom-designed columns and fixtures can be provided for larger loads or larger test articles. Contact us with your requirements.
