<![CDATA[Radiation Patter for NRF24L01?]]>Hi does anyone know where I can find info on the radiation pattern for the NRF24L01 modules with the on-PCB antenna?

A little curious, and like to know the best relative alignment of modules for best performance

Interesting read for newbies like me.
My interpretation of the data is that the best gain/sensitivity is in/from the direction that the leg at the end of the squiggle is pointing. Might do some open air testing when the rain stope and I work out how to extract received signal level info :|

I have put all the radios vertical and have been satisfied with the results
