[ARC5] Antenna current meter

Looking at the antenna relay/capacitor box, the meter is labelled something
like
'Antenna Current Indicator'. It is marked 0-10 with a more or less linear
scale, no
units. These units could be amperes (1.4A into a 10 ohm radiation resistance
would be about 20W), but the linear scale is suspicious.

Does anyone know what the RF current vs indication for the unit as a whole
looks
like?

Alternatively, does anyone know what the operator's manuals say for
indicated
current with the appropriate per-band dummy load should be (and what series
resistance said dummy loads present)?
