Why am I getting more antenna current in one lead than the other? I inserted an RF meter in each feedline before the antenna tuner. I believe that the current was about 1.5 and 1.7 R.F. ampere respectively at 3.870 Mhz.
First try exchanging the ammeters. If the problem is one of individual calibration or tracking - then that will reveal it - the problem will follow the meters.
Next - is everything exactly equal? Same leg heigth? Equal spacing at the *feedpoint* of the antenna? No large Metal Things near one side of the dipole?
I have the little MFJ crossed-needle balanced ammeter - the same thing obtains with my loop, fed with 450-ohm commercial ladder-line: one side draws slightly more current than the other. I attribute this to the fact that one 'arm' of the loop tracks under the back eaves of the house - the rest is disposed around the back fence.
