Topband: Base Loaded 160 Meter Vertical Vs. Helically Wound Vertical.

[Chortek, Robert L]

Hello Fellow Top Banders,
 
Does anyone have an opinion as to which of two antennas would be more
efficient, assuming the same ground system (8 elevated radials) :
 
1.    60  Foot Base Loaded Tapered Aluminum Vertical (3" - 3/4") with a
base loading coil (Air Core/8" in diameter) made of 1/4" copper tubing
with turns spaced about 1/4" apart; or,
 
2.    A helically wound vertical, a la the recent QST article?
 
Any thoughts would be appreciated.
