Very negative experience with this company.

Modulators 206 do not work on all TVs.
After reading your answer, I continue with the review.
I have been using another brand of modulators from another brand for more than 6 years, much cheaper, and they work on all televisions. I have more than 80 teams assembled.
Your sat department could not give me any solution to the problems I encountered with the 206.
A REAL FAILURE !!!
