I have a 4 tuner model Tablo. Got it 3 weeks ago.
I tried Mohu curve, and Mohu Sky. Also Terk Horizon.
I live in an apartment in Manhattan (10035) 7th floor.
Never got all the channels I wanted with Curve or Horizon or both with splitter.
With sky only got all the channels when in one position. I discovered it was because the metal of the connector was touching the metal window frame. This seemed to serve as a better antenna than the commercial products. Using tuner of my Panasonic TV with metal rod taped to the coaxial cable was able to get all the channels I want at the same time with clarity. With Tablo live TV and same metal rod taped to the coaxial cable (using with and without the Mohu amplifier) It does a lot of buffering, non-syncronized audio & Video. and pixelation. So I know great reception is possible but Tablo not processing it well. Tried all of the different recording data rates, with no difference.
Using Seagate portable drive 1.5 TB seems to work well.
Apple Time Capsule 802.11n & Airport express 802.11n are the routers. Tablo connected to express.
