Judging from the length, it looks like a low band VHF 2-6 Yagi with two folded dipole driven elements, probably to spread the useful frequency range.

Looks that way. Having each folded dipole very near a dipole element is one of the wackier things to me, but I'm not an antenna expert. Maybe just a way to transform 75 ohms to 300? I wonder how efficient this was?

It would be interesting to plug the design and dimensions into some modern day antenna modeling software.

IIRC, some marketing people dubbed this a "NEW, IMPROVED TRIPOLE DESIGN" ... Supposedly improved the impedance matching of the two DEs to 300 ohm line. jr |
