[QUOTE="hvdh, post: 1083678, member: 187415"] Over 10 years ago, sat dx'ers were struggling to get 2 Russian transponders of 40°E Express-AM1 with 100...120 cm dishes. Interference came from both sides: 39°E and 42°E. By placing small PVC pieces in front of the LNB, the interfering satellites were suppressed enough to get reception of 40°E. Maybe it will work in this situation as well (23.5°E - 26.0°E - 28.5°E). But in this case it probably must be shorter, because the satellites are less close to each other. Note that it could only benefit a fixed installation, because the piece causes some attenuation in the main direction as well! Grabbed below picture from dxtv.de (deepbluesky). I still have such PVC piece laying here, it's 5 cm diameter, 2 cm long, with two cut-out gaps of about 30°. [ATTACH alt="Bild031.jpg"]128562[/ATTACH] [/QUOTE]
