Agreed - I might pick a couple up and see what happens. My sat. runs from the dishes to the grounding blocks, then to the switch are relatively short so I think any attenuation there would have a minimal effect. I would probably put the GD units on the sat. side of the ground, is that correct?...Personally, I think I would consider experimenting here. I bet one built for cable applications would actually work. I saw a couple that were spec'd for 2.4 GHz.
