Hi All, I have rescently obtained a uhf pair of cavities that are not silver
plated inside (bare copper) They both have an insertion loss of 3dBIf I
were to get them silver plated what would the improvement be?
I have no idea how much it would cost but if the saving was only about 0.5dB I

I can't speak for the manufactures, but I think silver plating them would cut
down on the chance of the cavities oxidizing over time.
So that is why I would have them plated.
Silver plating can have an impressive positive performance effect under
some circumstances. It's also at advantage because it's corrosion
result is conductive, so performance is not effected by tarnishing.

Hi Doug,
One must always keep a real sense of humor to keep from
otherwise screaming at the lunatics I/we have to deal with

The key is to avoid giving the real lunatics your
