Copper Vs silver plated tank coil

(1/6) > >>

ke7trp:
I was told that a silver plated tank coil can have an increase of 10 to 15% effeciency as the Freq goes up.  I was told that on the low bands the difference is little.  I saw how my new J500 makes the same efficiency on the low vs high band and it has a silver plated coil.

Anyone every use this:

Its a do it yourself way to silver plate a tank coil.

Previous discussion on another board, the engineers conclude:  silver plating is good for cosmetics and corrosion resistance but makes no difference to RF below UHF because the layer is too thin to help surface effect.

ke7trp:
That is interesting.  The guy I spoke with did tests on his rig and saw improvement.  Thanks for the comments!    I know that as far as improving the efficiency, the plate choke is the first place to go.  The modern computer designed plate choke that is sold by RF parts, has produced BIG gains on my rig on the higher bands.  I just wondered about the plating.

I think the reason we see great performance on the high bands on our Johnsons is simply because they DO use high quality overrated parts in the tank, silver plated or not!!  Good engineering... they included 10 meters so they made it work right!

I AM OF THE VERY SAME THOUGHT
