[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...
