Often, currents introduced on the feedline shield will cause unwanted transmit RFI and received noise. With a ground-mounted quarter-wave vertical, regardless of the radial situation, but especially with poor radial systems, there is the need for a DXE-VFCC-H05-A Vertical Feedline Current Choke (VFCC) to keep current off the feedline.
