If the tower is 128 feet tall, just connect the center conductor of  
the coax to the tower and the coax braid to your radials.
If the tower is NOT 128 feet tall, you will need a matching network.
Lots of good info on this in ARRL Antenna Handbook.
Remember ... if the antenna is shorter than 1/4-wavelength, you will  
need some inductance in series with your feedline .. if it is longer  
than 1/4-wavelength [NICE TOWER!], you will need capacitance in series  
with your feedline.
Good luck
