Hi Ed.

Regarding your big 2-watt carbon resistors at 500 MHz -

what values of reflection coefficient or SWR were experienced when you
say they "worked fine". Can you remember? Or did you have some other
way of assessing "fine" performance?

The DC value has to be allowed a resonably large tolerance about its
nominal value and the HF performance cannot be any better than that.
