360 degrees or 180 degrees

You can treat the 360 readings taken as being spread over 360 degrees or 180 degrees.  Normally one would be measuring a beam that can rotate through 360 degrees, but there are cases when this may not be what you want to do.

If you are interested in plotting the signal strength of a satellite as it passes overhead and compare results of different antennas you may find the 180 degree plot useful.

To enable plotting over 180 degrees, select that mode by clicking the '180 Plot' checkbox.  If you want to plot 360 degrees then de-select '180 Plot'.
