Sorry brother snippits, the CMC choke is right below the wire #1 and is 8"-9".
In my post above...it was at some point confusing.
The model image of the Imax shown is about 30' to 40' away,,,with you standing on the ground.
Wire #1 is the radiator.
Wire #2 is the 36'mast.
The little red square, a little below the middle of Wire #1, is the 47 ohm capacitor that fixes the Imax pattern. This improves the radiator wire distribution.
The small red circle is the feed point at the bottom of the Imax.
The small bottom red square is the CMC choke that you describe in your post above, and again it is 8"- 9" inches below the feed point for the Imax.
The red lines are indicators of the current distribution and pattern. The currents vary in magnitude as to the distance the current is from the radiator and/or the mast and they are indicated by the current distribution.
Tell me what else you would like to know about this Imax model, or a question that I may be able to answer.
