Non that I have seen Chris, , there are high power MW elements , in
the KW ranges
the HF ones work on 477 , with a off set , 136 , more likely to of
given up by then
depends on the power , Ae matching and you need one of Jim's
scope match devices - see G4WGT web site c/w why not to use it on 477
..
other than that , ferrite ring and pick up coil , 50 load will be 1:1
match , so amps can be calibrated to watts , if your using class E/D
amp , then the DC power in is going to be say 10% more than the
power out ... other users any values ???
Sure Stephen will have some sort of emp proof measuring device,
may be a spark gap and tape measure :-)

Do any Bird elements give meaningful readings down at 136kHz? If not
are there any commercial alternatives to building something? Thanks.
