[Elecraft] RF Ammeter

[Ron D'Eau Claire]

Jim, I sent you direct the construction info on my 0-100 mA and 0-1.5A RF
ammeter that includes photos and schematic. I hope your e-mail system allows
the attachments. If not, let me know. 

This is an in-line ammeter, not a clamp on type.

As everyone knows, "real" RF ammeters are becoming scarce,  or very 
expensive.  Does anyone out there have info on where to find a circuit 
that is relatively inexpensive that I could use as a substitute?  
Something using a toroid core plus diode, or something like that,  would 
be what I am looking for.   Not too complicated in any case, and  
absolute accuracy is not needed - a relative indication would be fine.   
The application is measuring RF current for a trailing wire antenna  
from an airplane.    Transmitter power is in the 100 watt range.


Thank in advance
