CM Input file (NEC-2) for an interlaced combination of a 2-element yagi (40 m)
CM and a 3-element (20 m). This is a model to give max F/B on the same freq
CM (7 MHz) as measurement done 970524. To achieve this the lenght of the 40 m
CM elements are changed frm 7.355 to 7.22 and 7.105 to 7.11 m.
CM The 20 m elements are the same as that optimized before in NEC-2.
