AIT-600-06 vs. AIT-600-06R Tuners

Updated: Sep 28, 2021

Similar spec tuners. Different cases. But what's the difference?


The Model 06R is a larger, stand-alone case allowing a more robust design. It offers more space for the tuning chamber, i.e., for the capacitors and the coil to have more space around them. For that reason, 06R model offers better performance for a variety of applications. It offers great results for deeply capacitive applications that are especially tricky. 

The coil in matching devices must have free space around it and be away from the side metal panels and metal covers. If not, it loses RF energy to the grounded walls. 

When RF power reaches over 300W, losses from the coil to the walls are causing change in the coil inductance and the matching starts getting out of tune causing several Watts of reflected power. 

T&C offers both units depending on their application, but we recommend to use 06R with 600W RF generators. For continuous operations around 600W RF power, the narrow case is not recommended. Performance will be reduced and inconsistent in some applications. The price difference is only a couple hundred dollars more and the time saved in achieving great results quicker will be worth it. Mounting holes/kits are available for both units.

From the customer:

"Most of the customer’s chamber impedances are not available [to us], RF matching is by luck sometimes. So AIT-600-06R will be preferred from now on."
