The 229 and 238 (essentially the same tuner in a different color 
case and with their dial cords wound in the opposite directions) are 
really excellent tuners, and can be tuned to match almost any 
reasonable antenna. Sometimes, if the antenna is far from 50 ohms 
resistive, it can take a while to find the match. And if it's TOO 
far from 50 ohms, you may not be able to match it. I've had this 
happen when the antenna is a half wave vertical on 80 or 160, which 
is a VERY high impedance. 

TenTec supplies a capacitor that you can connect between two 
terminals on the back panel to extend the tuning range of the tuner 
on 80 and 160. That solves the problem I described above.
