Hi all,
Has someone ever build (homemade, not bought!) a Rogowski-coil for
RF current measurements?
https://en.wikipedia.org/wiki/Rogowski_coil
It could be used to measure leakage currents in a tower near the
antenna wire for example. Or for measuring RF currents into a pole
of a guide rail, for example :-)
I'm planning to build one and i thought i use 0.4 mm diameter
enameled cu wire arround a graden hose, having 0.6m circumference.
Then some shrinking tube will be applied. That's the plan.
The circuit looks easy, it should be run from a 9V battery and a
simple TL081 for example. The output could be adapted to a
multimeter, so there is a digital read-out.
I'm curious to see how it works...
73, Stefan
