Neil is correct and adding a new component to the system won’t help. You might take another look at the antenna pamphlet and check the section on tapping your matching coil.
Using the formulas on Page 5 you can calculate the inductive reactance of your main loading coil and determine the 50 Ohm (or any other impedance you wish) tap. In this way, the impedance of your connection will match your transmitter, improving the performance of the return side.
I have found that connecting the coil this way does improve performance noticeably.
