OK before I get a shed load of abuse Please note, my math is not perfect and this is only a partial explanation that will try to show the relationships between the frequencies shown, and it's not to be taken as the definitive answer. ( this is my understanding and it works for me).

The impedances top and lower readings are to demonstrate possible readings and are not necessarily a true reflection of the values you may find.

In short this video is intended to help explain how dual band antennas work.

I'm still learning and any comments to correct or confirm my belief are gratefully received.

P.S. do not take my word for it, give it a go for yourself.
