Tuned Dipole Antenna Element Lengths

Just as interference testing requires RF enclosures, isolation systems in turn need their own testing. This document reviews some of the issues and considerations in testing RF enclosures.

Half-wave dipole element lengths

Overview:

half-wave tuned dipole antenna showing quarter wavelength element with respect to a wavelength. Half wave dipole antennas are typically used for site attenuation measurments, shielding effectivness and as a gain reference antenna. They are the simplest and widely used class of antennas. The tunded dipole antenna consists of two quarter-wavelength telescoping elements placed end to end for a total length of approximately L = Lambda/2.

This is the proper adjustment procedure for the dipole antenna series and the resonant frequency/element length chart.

To use your tuned dipole antenna, you must set them up either on a tripod for informal testing or on an antenna mast for site attenuation and/or compliance testing. The telescoping elements should be adjusted to the resonant frequency (1/2 wavelength). When adjusting the elements make sure that the largest OD is exposed.
