An Antenna Analyzer is more then a SWR meter. An Antenna Analyzer can help maximize your antenna system's performance. An Antenna Analyzer can help you find problems in your antenna system. SWR is an indicator of how well the feed line is matched to the antenna. If the Impedance is 50 ohms but, the SWR is not 1.0:1.
