vertical 1/4 wl

1/4 wl radiator and four ground radials bent down at a 30 to 45 degree angle to present a 50 ohm impedance match.

direct feed no matching network required,

Use an RF choke or line isolator, ferrite beads over the coax or whatever your choice is for preventing tvi rfi .

Marconi has does some modeling and posted his results on the 1/4 wl ground plane.

The starduster is about as close to a balanced vertical you can get commercially for sale. that little ground plane works great.
