Thanks for asking - I have following set
Antennas Direct ClearStream4 HDTV Antenna
40-Inch Antenna J-Mount, Mounting Hardware and Sealant Strips included
I installed this antenaa, mounted on this 40-in antenna J-Mount, then temporarily connected it to one TV with antenna inside the house. I am getting pretty good signals with just that try.
So right now I try to mount this set to my HD DirecTV antenna mounted on my house roof.
