| So the values on the chart are only applied where the concentric circles meet the plotted lines? e.g.- the 0 db straight out, the -2 db line meets at 30 deg off of the centerline, -4 at 40 deg, -20 db at 80 deg, etc? | ||

| Can anyone describe how to read an antenna polar plot diagram? I am pretty new to all of this. I understand the basic look of the thing, but don't understand why the dB start at negative 30 dB and go out to 0 dB. I'm reading through the ARRL book and it doesn't explain it at all; and surprisingly the internet is no help. Thanks. | ||
