RE: Antenna & Servo leads, how close is TOO close?
By definition, alternating current is periodic reversals of current flow. The waveform is irrelevant, it may be a sine wave or any other waveform if there are periodic polarity reversals.
In some cases it does make a difference. I was trying to be humorous but got a lecture I really wasn't requesting. I had 30 years in the elecrical & electronics business and am quite familiar with design considerations for ac, dc, pulsating dc, harmonic distortion, etc.
Please spare me
I will now take leave of this thread.
