Well, according to Antennas Direct it’s Multi-Directional and the way it’s pulling in stations I would concur. Indoor/Outdoor TV Antennas for Digital HDTV - Shop by Style | Antennas Direct
As stated in my previous post here, it’s UHF and yes it’s a different direction from which it’s aimed. The Chicago Towers are 90.59 Heading, 58.33 mi away. The Rockford/Freeport Towers are 319-323 Heading 34-36 mi away according to AntennaPoint.com. I agree, adding another antenna pointing towards the Rockford/Freeport Towers would definitely improve the signal. However, I’m finding going directly in to the TV with this KT-500 it’s pretty solid. I’m even pulling in 6 more Stations than I was previously so I would say the KT-500 is doing it’s job. I think the signal strength is on the threshold for the Tablo causing it to wack out even though it’s showing Green in the Tablo signal strength.
