Generally hydrogen thyratrons are not used for tube coils.
One could be built that way, but it would not be a traditional design.
The usual way to build a tube coils is to use vacuum tubes; either
power, or transmitting types.
Richard Hull has done some work with classic TC's by replacing
the spark gap with a hydrogen thyratron. This however is not a tube
coil in the traditional sense. It is a tube coil in the sense that it uses
a tube however.
The traditional circuit for a tube TC is quite different than the circuit for
a spark gap TC. In a spark gap TC, the spark gap is in series with the
resonant tank circuit components. In a traditional tube TC, the tube is
external to the tank circuit. A spark gap TC (or a hydrogen thyratron
based TC) uses a damped wave. A traditional tube TC produces a
continuous wave RF output.
