The antenna is mounted on either an antenna mast (such Model AM-400) or an antenna tripod. The coax cable is used to connect the antenna to the a measuring instrument.

Theory of Operation Functional Block Diagram 3.0 Overview This section describes the theory of operation of AD-100 Dipole Antenna. 3.1 Theory of Operation The tuned dipoles are standard antennas used for calibrating Open Area Test Sites (OATS), EMC measurement and as a reference antenna for calibrating other antennas. - Page 11 Due to the fi nite diameter of the elements, the optimum or tuned length of the dipole is found to be slightly less (approx. 4%) than determined by calculations.
