Message: [QUOTE="Piggie, post: 40745, member: 2941"]I agree that you need a calibration sticker to give calibrated results.However a calibration sticker is a comparison itself to a calibrated source. Thus if you use the same meter to compare two antennas you are doing the same thing and the results are accurate. One antenna becomes the calibrated source, then the second antenna becomes the measured quantity. So yes, I agree this doesn't mean you can say his results show antenna A to have exactly x amount of db on a given channel.  But it will show which antenna is stronger.   So yes, you can't be sure without calibration how much better or worse one is against the other, but still it will show a relative difference across the two antennas.So I don't consider the fact and he admits it's not calibrated to be any way a reason to discount or consider his work moot.[/QUOTE]
