And the wonderful thing about antennaes is that you never know what 
you will wind up with when you start!!  And making them work despite 
all the odds is fun!!
My first antenna was on a thirty-five by 140 city lot in chicago.  A 
Windom fed with 300 ohm TV twin lead.  Made that antenna work quite 
well connecting the feedline together at the base and running it 
through a tuner.  The teenager learned a whole lot by trial and error 
and that info has served me well for all these years of antennaes and 
experimentation.  Now it's a W5GI Mystery Antenna and a Carolina 
Windom in a wider, deeper suburban lot west of Chicago.  And a ground 
with a couple of decent radials and a string in a spot to pull up a 
piece of rope attached to what will be an inverted, base loaded "L" 
for 160.  Won't be a Globe Scout on A M but it will still be fun.
