Antenna Measurements

last updated 29 November 2023.

We can take many different types of measurements in the process of building and using antennas, from the dimensions of the parts, to adjusting the match to the feedline, to comparing its performance against a reference antenna when the signals are received on a different continent. This section looks understanding the purpose of various measurements, along with the equipment use to make it and how to interpret the results.

My philosophy on units and tolerances.
