Rick, I read with interest about the CCD antenna. I understand to shorten an
antenna you us series C. In this case it is apparently intentionally made long
and shortened with C.
I tried a 20 meter full wave in my cad program. (MMANA)-GAL) I put a cap every
1/8 lambda. I tried the automatic optimize and manually adjusting C to no
avail. R never came below a thousand ohms but was able to get Xl to a null and
gain at 7 or so DBI. Although all the components were symmetrical it became
directional and height did effect it. Not having any of the ARRL Compendiums at
hand can you give me a hint where the C is applied? I think I would like to
build one if I can get the model to work.
