Friendly Service from De Forest
During my Holiday in Ireland, I was successful and got a set of De Forest coils.
The Label on those coils is very useful.
There is a Diagram were you can easily read what will be the wave length in relation
to the related Capacity between 0 and 1000 pF.
Nice also: What are the wild Waves saying

Sorry, but I doubt deForest. such coils were made by Igranic.
The DeForest Honeycomb Coils with their typical pin/jack base are an invention made in 1919 by Robert F.Gowen, Chief Engineer at DeForest.
