Impressive installation you have there. I wonder which frequencies you can get from fringe satellite beams.
In particular:
The first question that comes up is, where in Iran you are located.
62E: Since you are in the center of the S1 Beam i suppose all frequencies beam in quite strong, even so far on the edge of your dish, right ?
53E: Full reception of all frequencies ? The S2 Beam looks stronger in SW Iran, on the other hand the S1 Beam in the East looks better. What about Wide Europe ?
42E: How about Türksat 2A/3A West Beams ? The footprints show signal degragation in moving southeastwards.
39E: Anything except of S2 Beam frequencies locked ? I doubt it since footprints of F1/F2 Beams end in Syria but who knows ?
36E: Do you really get some frequencies of W4 Russia Beam or did you mean Eurasia Beam of W7 that covers officially whole of Iran with plenty signal ? Anything of W7 Russia Beam as well ?
31.5E: Which frequencies can you get from here ? The interesting ones are on the West Beam and officially Iran is not covered. Do the real conditions differ so much ?
25.5E/26E: Any frequencies you cannot get except of those from Badr 5 Maghreb Beam ?
21.6E: Full Wide Beam should be no problem, right ?
19.2E: Can you get all of Astra 1M Wide Beam or do you miss any frequencies ? What about Astra 1H ? Members from Tehran have reported that it can be partly received on 1.90m, so maybe some few frequencies break through even on your dish ?
16E: Anything missing here except of course the Madagascar Beam ?
13E: Hotbirds 6/8/9 should be fully present, right ?
7E: Do you lose any frequency of W3A except of the Africa Beam of course ? Can you also get some frequencies of Eurobird 9A as well with this LNB ?
4.8E: Europe BSS and worse FSS look to fall rapidly towards SE Iran, so can you get all from these 2 Beams ?
0.8W: Suppose all Beams are dead except of Intelsat 10-02 Spot 2, right ? If not please let us know which frequencies you receive.
4W: Any frequency you can get except of Amos 2/3 Middle East Beams ?
7W: Atlantic Bird 4A should be ok, right ? But are you missing any frequency of Nilesat 101/102/201 ?
12.5W: What about the Atlantic Bird 1 Europe Beam frequencies ? Since this LNB is far in the offset of your dish, the gain should not be too high. Which ones do you lose or get ?
Finally i would like to ask, if you've tried to fix another LNB for 15W as well.
Thanks in advance for clearing up what is possible and what not.
Best regards and always have well reception without disturbances from the local authorities.
