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...
