Perhaps there is a question of semantics to say that a 0.08 
wavelength vertical, which has about a 2.5 ohm radiation resistance, 
qualifies as a "fairly good" antenna on 160m?

With a 5 ohm ground system, which is probably better than the average 
ham will install (something like 30-40 quarter-wave radials, 
depending on local ground parameters), 2/3rds of the transmitter 
power will be lost in the ground system (-4.8 dB).

It sounds like Frank wants less competition and QRM in the next 160m 
contest.  ;-)
