I currently have the working setup as shown in this image. The Dish installer used a HFS-2D splitter to put another RF antenna closer to TV2 for the remote control. Now I want to split off another television to be a mirror of TV2. It's not practical to use a three-way splitter (HFS-3D) because of the physical locations of TV2 and TV3. Can I simply insert another HFS-2D as shown here? Thank you!
