Good Morning.

The solution I use here to tune radials is to insert an RF Counterpoise Tuner 
(TT-1251) between the coax shield and radial system at the antenna feed 
point. With low power on the antenna adjust the RF Counterpoise Tuner for maximum 
current as shown on the meter display.

Or, you can use RG-58PE (vf.66) to make your radials electrically measured 
for 1/4 wave as shown on your MFJ-259 (page 30 of users manual and as shown in 
ON4UN's book). This method is very accurate and results in the radials being 
30% shorter in length over using wire.

Give it a try. It works very well.
