ok eric, an 18ft dipole is pretty short but will work.  how far from 
the end of the wire is the loading coil?  if you need to change the 
length of the ant, the wire after the loading coil that goes out to 
the end insulator is very important.  how much wire between the end 
of the loading coil and the end insulator?  how does the coax connect 
to the dipole??  you might be better off with a center loaded dipole 
and use inductive coupling to it.  how much room do you have on the 
balcony?  how long is it?  take care, c u mike
