@brg88tx The 2-tuner and 4-tuner Tablos are the same. Here are some of the details I think you’re looking for:
The design of the dual and quad tuner Tablos are nearly identical (other than the quad being slightly heavier due to the additional tuners).
They both use a 4-way output on the board. We’re actually using an amplified splitter which negates the db loss you’d usually see from a split. The key difference here is that the dual-tuner is using 2 of these outputs (though it’s already been split for 4), and the quad-tuner is using all of them. We tested this extensively during design and production, and we consistently saw the same results.
There’s been some confusion about this, and understandably so; at first glance more tuners = signal loss makes sense. However, in this case, we’ve designed the Tablo around this case so that we can see the same performance between the two models. Hope this helps!
