Software : Grid Bearing and Maps
- Freeware antenna software that lets you see what the polar diagram of your rotatable beam actually looks like where it is operating.
With PolarPlot you can measure the polar diagram of the antenna and check for abnormalities - compare plots taken before and after changes to the design or location - check the -3dB beamwidth - look at the front to back ratio - see the size and position of the sidelobes.
