The choke balun is used because the G5RV is fed with balanced line. They
work well, last a long time and require a tuner. I have never had any TVI
with one, nor did I ever expect any.

The G5RV antenna can be found by googling. Anyone using this
arrangement. It uses a coax feed to balanced feed (which variously acts
as radiating elements, depending on the band). The author says a balun
is not needed but then describes an RF choke that sounds a lot like a
balun. I am also concerned about TVI with this system.
