F5 where is the 4th harmonic

In the F5 manual a spectrum analysis is presented and the text says "...you can see the dominant 3rd harmonic, as well as 2nd, 4th and 5th."
But the 4th is missing ... ?

Also, R4 in Figure 5 should read 600, as mentioned in the text.

Well, R4 might be just a typo but the spectrum analysis is a screenshot from an actual
measurement with an AP, I believe. If it shows no 4th than there is none. I just wonder how and why this is the case.

I know, and as I found out this afternoon it's actually being mentioned in the 4th reply to the "F5 power amplifier" thread. I just thought I'd chime in. Sorry.

Sorry, I forgot the 4th harmonic. I'll remember to include
it next time....

:cool:
