Chris,

The arrangement I have here comprises a 5A FSD RF ammeter between the 
transmitter and the antenna isolating transformer, and another such ammeter 
(switchable between 5A and 500mA FSD) between the isolating transformer and the 
earthy end of the antenna matching network.. The intended impedance at this 
point is 50 ohms.

Hope this helps, John
