[IRCA] SHORT VERTICALS

["Mark Durenberger Mobile" <Mark4@xxxxxxxxxxxxxxx>]

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...
