Indeed there is one element from 0.2-0.535 MHz (power range from 10W to 10kW
full scale)
but only for the 4410 Model.One element covers 7 power ranges.
The elements fo the Bird 4410 Model are not compatible with the 43
Model,however.
The 4410 Wattmeter is quite rare to find and much more expensive than the
much more common 43 Model.
