Tom,
Great work by you and W0QE. After you met with CenturyLink's leadership
team, did they develop an action plan for a final resolution of the problem?
Congrats to Larry, W0QE for creating a shared PC board of his Hi-Z
amplifier. I just purchased a set.
For folks who aren't skilled with SMD/SMT work, one alternative is the DX
Engineering (DXE) active vertical antenna. It would require some mechanical
tweaks for fitting onto a magnetic base. According to the latest DXE
catalog, a similar version that was developed by Jack Smith, K8ZOA (SK) will
be available later this year.
Paul, W9AC
