[TowerTalk] End feeding a half-wave vetical

I doubt that a 9:1 transformer is going to do the job... The impedence 
at the end of the half wave is several thousands of ohms and is highly 
reactive - plus lthe reactance changes rapidly as the frequency is 
varied... All is not lost, however...
  A parallel tank circuit with a tapped feed point at ~ 50 ohms above 
ground for the coax will get you home free...  It's been done that way 
for generations...  Check any ARRL Antenna Handbook...

cheers  ...  denny - k8do
