Also forget the complication of trying to trim the cable length...  the effects of temperature,  humidity,  pressure,  moisture, etc in commercial TV cable being used at microwave frequencies will rather quickly render your precise adjustments moot. 

----------------------------------------

Forget the complication of an impedance transformer just trim the cable 
to the appropriate length by adding a short section of additional cable 
if necessary.
Unless the SWR (or reflection coefficient) of the antenna and the 
receiver are measured using an impedance transformer may make matters 
worse.
