Resonance in Moxon Yagi on NanoVNA

Moxon Yagi for LEO satellite operations has elements for VHF and UHF, but only a single feedpoint. Driven element and Reflector are Moxon VHF elements. Driven element is split in the center and connected to the feedline. Five UHF director elements have no physical connection with the feedline. They are just passively coupled. Advantage is that there is no need for a diplexer. Feedline is directly connected to a full duplex radio like my IC 2730A which has a diplexer inside.
