Ok, I had the Mohu Leaf working for almost the entire house using the DirecTV cable in and with 2 indoor antenna amplifiers on the HDTVs. The signal was almost strong enough just by putting it against the side of the house facing the station antennae (according to AntennaWeb, even though we’re about 20 miles out from the station broadcasts. One downside was that the paper thin design was too prone to being blown around by storms.
Decided to upgrade to the Sky and have it “mounted” on the inside of our privacy fence (with open air in the direction of the antennae). I plugged the amp into the 4-way splitter and removed all other amps. We’re now even getting the obscure channels.
