I ran the same model in 4Nec2 as below but changed the hat from the traditional two wires to four, spaced 90 degs. Complex base Z is near 16+j0. Even though two symmetrical top-hat wires produce little radiation, four wires result in wires that are only 24 ft long to achieve resonance -- versus 41 ft with only two wires. Getting to six would result in a smaller top hat but may not be worth the mechanical hassle.
