Multi polar diagram

[G0HWC]

Hi all,

is there a way of saving muti polar diagrams ?
and if yes can they be overlayed over each other ?
while working on my antenna it would be handy.

I don't think it can be done within the RB program - though I stand to be corrected. What I did was saved screen shots with the different polar diagrams, than superimposed them onto each other using Adobe photoshop.

Your polar diagram data is saved in the D0012.dat in the "data" directory of the AirNav install. You can save it whenever you like

tarbat has created a excel spreadsheet to graph the differences for you - refer to this message: http://www.airnavsystems.com/forum/index.php?topic=1302.msg10127#msg10127

I'm with eggplant on this. For antenna comparison purposes, screenshots are both simple and effective.

I output ANRB to planeplotter - leave permanent trail.   When testing antennas any changes can be logged in planeplotter saving each change as a different colour - more effective than polarplot

To really understand your antenna performance, I find Overflight Logger gives the full picture, showing reception at all points and altitudes.
