Quality of Bolt's OTA Tuner

I have seen mentioned here and on OTA boards that the Roamio's OTA tuners are not very good and that in my area I might get only 50% of the stations that would be available if my antenna were tied directly into my TV's tuner.

Does anyone here know if the Bolt uses the same tuner or if the one in the Bolt is improved?
