The calculations are for any dipole length over any frequency range for any rotation sequence. Be advised the calculation can b[...]

50 Once you have saved your dipole array into REG1 (or 2,3,4) calculate the Aperture array and save the results into REG2. Now use the calculator to multiply REG1 x REG2. The result is the entire link gain normalized to the Rx antenna gain. Save the results into a REG3. Now choose a receive antenna. You could go back into the dipole section and cal[...]

51 Data Processing Feature Group Delay Function Group delay is the derivative (slope) of the transmission phase angle. For passive circuit elements the group delay is linear and may be calculated from two measurements.
