The main difference between the Tablo and a traditional TV is that the Tablo has multiple tuners - so that you can watch and record multiple shows at once.
The drawback here is a small loss in DB when the signal is split. We use amplified splitting technology to mitigate for this loss, so it’s nearly negligible. In some rare cases, you could have one channel on your TV that doesn’t appear on the Tablo.
My antique antenna is outside, up ~25’ with an amp-splitter one run is split between 2 TVs and a Tablo Quad. The other is a 50’ run to another TV and a Tablo Dual Lite. I’ve 40-60 miles from any transmitting tower. Even when my cat would lay on my tablo Tablet too hot and - #11 by djk44883 it made no impact on it performance.
If you have a good quality signal, a split here or there shouldn’t drop it enough to loose the channel from what I can tell. There are a lot of fear-mongering about splitting though.
