The main reason for this e-mail is to ask this question, "When I have looked at designs in amateur radio magazines or internet for a clip on RF Ammeter the designs seem to be limited to 2 ranges (100mA & 1A FSD), is there a limit to the range of this type RF Ammeter or can the ranges be extented to say 5 Amps maybe? is there a calculation to extend the range ?" My LF antenna seems to be showing in excess of one Amp so I need an RF Ammeter with a greater range than 1A. 73 Gary - G4WGT
