I think you hit the nail on the head. The G5RV is a dipole with a matching network that gives it some acceptable properties on bands other than the band on which it works like a dipole.

Using the same radiating element with a different type of matching network (a tuner) and using low loss transmission line all the way from the tuner to the antenna (ladder line) is an even better way to drive the same radiating element.

Bottom line, Dino, enjoy your Random Length Wire On All Bands But One, Antenna With Low Loss Feedline And Tuner and have a blast. We could call it RLWOABBOAWLLFAT, but "modified G5RV" sounds better. It's also easier to send in CW :-)

... but Dino, if you remove the coax/balun/twinlead then the antenna is no longer a resonant antenna system on 20 meters, as designed (e.g. it's no longer a G5RV). It's just a random length dipole fed with low-loss ladder line by an antenna matching network. No rocket science there.

The advantage of the G5RV is that it's a resonant antenna that exhibits some gain in certain radiation lobes, but only on 20 meters. That's all Louis ever intended it to be, I believe. Everything else written about the antenna is marketing hype, IMHO. But you don't have to take my word for it; go back and read his article in the Compendium instead.
