It's not really a G5RV jr anymore. It's a somewhat oddly cut dipole fed with ladder line, but it is certainly true that I do not know how it is radiating. My installation is not perfect either. The two ends are coming down at different angles, and is bent over a tree branch and turns slightly. So, really, quiet a mess. It does hear pretty well, though!
