Re: Topband: raised radials

["Carl" <km1h@jeremy.mv.com>]

You ever wonder why a few on here are so much louder than their competition 
with similar installations when 1-2 keep trying to make us believe it has 
nothing to do with the radials beyond a small number? IF he is correct then 
why the big difference? Anybody care to offer a guess?
Or the fellow on a city lot that knows he is 10dB below the guy a mile away 
out in the country with a big vertical or T with lots of long radials plus a 
base mesh....after several years of comparisons. You dont need fancy test 
equipment to see that.
Ever wonder why photos of elevated radial BC antennas show a base mesh and a 
small number of radials? And then performance tests require a reduction in 
power to conform to the canned 120 radials in the ground benchmark signal 
strength. Or due to the stations original certification with a full set of 
base radials that rotted away and the elevated are the replacements.
Or the person on here who went from an extensive radial system to a full 
screen claimed a 5dB improvement but now denys the possibility. Its in the 
TB archives from 1998.
A few seem to be in a continuous rut with impedance the only factor they 
seem to mention. There is a lot more than just the immediate soil under the 
radials that is involved when it comes to field strength many wavelengths or 
continents away which also affects the energy in a particular elevation 
angle.
