Adding 2nd monopole onto cantenna to improve signal reception

Two monopoles at 90 degrees in cantenna

One connects to splitter immediately

Two connects via coax either 1/4 wavelength or 5/4 wavelength (more practical length = 26.5cm x 66% (velocity factor of coax)).

Can use NanoVNA to measure it.

Does not increase resolution but doing this improves reception in a similar way to increasing integration time by x1.44.

A possible design is below – still being discussed to determine whether this is viable or not:
