In your dreams.
I'm dreaming of The ARRL Antenna Book, 15th edition, page 8-6. Spacing 1/8WL,
phasing=135 deg, Gain = 4.1 dB. Remember, this is for two 10m verticals mounted
in line with the vehicle, not one on each side of the vehicle. It is essentially
a two element vertical beam with a cardioid radiation pattern and a large
front/back ratio.
