Hello, this is my first post. If I've miscategorized this question, please redirect it. I am new to this, but please know that I've been researching and researching for a very long time, and I have seen other threads similar, but not quite exact - and I honestly could not translate that into exact what I'm trying to do. I see 10 different answers per thread and it's gotten me so confused about this elevation angle I honestly have to ask directly. Some have said just try and play around with it, and I have - but with no success, so here I am.
Notes:
- My wild guessing randomly picked up 99W Galaxy 16 ABC Puerto Rico once, and I can't tell you how but since I've moved it I could never get it back.
- I also have an existing tiny (36 cm?) Ku dish that I know works and was able to pick up 3 community service channels on, to prove my openbox was working.
Setup:
-1.2m Offset dish (required for the satellite I want according to satbeams was 110 cm, so I'm fine - since ABC needed apparently a 150 cm dish to pick up and I did it with a 120, I feel I should be able to easily get the satellite I want that requires a 110 cm dish)
- Combined C/Ku band LNBF (I only really care about the C-band though, the Ku is just a bonus)
- Fixed (albeit moveable if necessary) mount
- Openbox S11 which I programmed all the transponders on Dr Sat/Lyngsat/Sathint into
- I have added all C transponders to one list with what it called "LNB Freq" set at 5150, and the same with close-by Ku transponders set at 10600 and separate at 10750
- I removed the external diseqc switch altogether and directly connected to JUST the C-band (lower) LNB output
- Want to hit Anik F1r at 107.3W / 29° elevation
- Dish has 24.62° offset
Okay so this is my setup, please tell me if anything above is wrong. The main question I have though is definitely this problem....
I have heard/read a dozen different ways to set offset dishes upside down. Why do I have to set it upside down? Well, I need 29° elevation, and if the offset is 24.62°, then that means:
29° - 24.62°= 4.38° ... which is impossible, it just wont go that low. There's a bar to the base that it hits. (If that's not how it's calculated, please let me know) It makes sense to me because the mini one is essentially vertical.
So I needed to put it upside down, and through my research found multiple answers.
1st: 90° - 4.38° = 85.62° (this one said that by rotating the dish so the lnb was on the top then you just count the offset angle bracket from 90 backwards)
2nd: 29° + 24.62° = 53.62 ° (this one basically said, since it started at -24.62°, to get it to "zero" you'd have to add the offset of the dish; IE 24.62°)
3rd: 24.62° x 2 + 29° = 78.24° (this one I didn't even have a clue why it was double, but I assume maybe it's because the angle is based on 90° times 2 and totating the dish 180°, IE upside down to get equivalent of 180 degrees instead of the 90 scale on it you have to double it, but I really could be waaaay off)
4th: That it's simply 4.38° , since it's only rotated 180 degrees and it's just reflecting off the bottom instead of the top...
The first and second made the most sense to me, but alas I never did manage to hit Anik F1r. I really don't even need to know WHY which method works, just please let me know which of these is applicable. All I did is rotate my dish (not the angle bracket or anything else) exactly 180° so that the lnb was on top and not touching the ground sitting at 12° which was still too high since I needed 4.38°....
Thank you so much in advance, and sorry for the long ramble - I just want you to know what I have so it can be applicable.
