- Now, that IS interesting! Does NEC tell us that there isn't an end-null in an end-fed half-wave's's near field? Is the coupling purely capacitive to the adjacent feedline conductor? Cortland

- When you drive 1 amp into Wire 1, NEC tells you how much current flows in Wire 2, but it doesn't tell you why or how. Not absolutely certain (it's getting late over here). -- 73 from Ian G3SEK 'In Pr

- We can account for common-mode current here without recourse to induced fields. We must provide a relatively low impedance for the matching circuit return. There could be perhaps 20 volts on this ret

- Jamie, I am willing to bet that your RFI problem is a proximity issue. I have the same thing. A tribander 50 feet above the shack and the same tribander on a second tower located 100 feet away and 10

- I for one have been educated which is never a waste of time for me. I have had a similar odd problem in the form of qrn from AC power line noise. It's odd because at its worst, I rx it on 20-80, and

- Hi Ian, Thank you for your investigation--no apology needed; I appreciate your comments as they have been a big help in my understanding. They were facinating, particularly the 20% increase with a do

- Me too, so I've been forced to learn more about this subject than I'd ever wish to! - or else they blame the amp, and it shuttles back and forth uselessly to the manufacturer. Part of the difficulty
