Just got the 20th edition of ARRL Antenna Book and the "thing" about current in
loading coils is perpetuated in it. Actually, book contradicts itself. On page 16-4 Fig 7 shows rough current distribution with center loading, showing drop across the coil. On page 16-7 Fig 10 "sticks" to no drop in current across the coil, proclaims "stretching" the current by the coil. The shaded area is back, it actually represents the current coming out of the coil, but the reality is lost in the formulas. My experiments were grounded by lousy stormy weather and flu, mybe I get the web page spruced up. Merry Christmas everybody, that includes Art! Yuri |
