Default Is an Antenna Analyzer an FCC violation?

My understanding is that the popular MFJ antenna analyzers generate
around 2 volts RMS of RF at their output port. This works out to
around 80 milliwatts into a 50-ohm load... comparable to what a small
QRP transmitter would deliver.


However my measurements of an MFJ-259B and an MFJ-269 both show constant
output throughout the frequency range of +7.0dBm +/- .5dB which is 5mW
and not 80mW.


Interesting - thanks, that's quite a bit lower level than I had
[obviously,mis-]remembered. That'd be about .5 volts RMS rather than
2 volts RMS, IIRC.
