I think we may be glancing off each other. You're reporting your research at component level and I'm alluding to design in the context of effect.

Where we meet in terms of your reply, is the reflection coefficient. Presumably you've used industry data for the components involved - the RC (nor anything else) is not given in any SH/Netgear spec. If there is impedance mismatch to the extent you mention, then the complaints we see about wireless performance are explained.

I'd call that bad design - to pput anything in the field that has such severe characteristics.
