Easing of SWR of 8 element CoCo by adding a 1/2 element (1/4 wavelength) at top, and shorting its core and braid at top
By adding a 1/2 element (1/4 wavelength) at top of CoCo, and shorting core with braid at top,** the SWR eased from 4.61 to 3.62**
Yes, it is an improvement, but not sufficient. We still need to reduce the SWR from 3.62 to 1.5 or less.
