[IRCA] SHORT VERTICALS

I'm wrapping a 2,000-mile road trip and have occasionally stopped, to stick
up my 30-foot modified Dallas Lankford vertical. And something's been
bothering me.
Lankford's heritage 'short vertical' proposes a 4:1 base match. I've played
with this ratio, from 2- to 16- : 1 and, indeed, 4:1 seems best. That would
suggest about a 200-ohm antenna.
But why? 30 feet at MW = about 200 ohms? Doesn't seem right...
Scratchin' my pate and anticipating wisdom from the list...
