I see your point, and that's why I posed the question. Perhaps I need to clarify. What I was thinking of was to test each leg, treating as a longwire, and coupling directly to the end of it, not via feeder.

Does your argument imply that you could not resonate a longwire antenna with a GDO, but only a dipole?

But, in terms of erecting an inverted V where you know the two legs are not in perfect free-space, but are affected by quite different surroundings (trees, buildings), maybe you just have to proceed by trimming each leg to the same length?
