Why is the dish rotated?
Last time I checked, that's normal. My 90 cm on a HH90 rotates like that.
Is that the correct bracket from SatelliteAV?
It's the bracket that came with the dish.

Johnny, try this: Aim at 99w, whatever your strongest signal there is.
REMOVE the conical scalar completely from the lnbf. Tune the lnbf forward / backward, and even twisted whatever degree it must be for 99w at your house. Try to get absolutely ALL the signal you can gather that way. Tighten it all down when you think you've got it. Double-check it to make sure nothing changed when you did the last crank down. THEN re-install the scalar. Do NOT touch the lnbf's position anymore, only slide the scalar in or out, and see if you can peak the signal even more.
With a smaller dish such as this, it's going to see probably around 5-6 degrees of sky. Since the satellites are only 2 degrees apart, that means sats to either side can interfere, depending. I bring this up, because that ALSO means that maybe pointing slightly to the LEFT or RIGHT of the sat you actually want to get, might work better!
In other words, you want to slightly "detune" any possible interfering satellite to either side, yet still get the signal you want if possible.
This is what mine looked like with a C-band LNB on it:
Seems quite complicated , but at the end of the day, if it works, why not.
And it is friendly dog, friend of you!

TBH, I have no idea how to measure performance. But if I say something like "it performs well" I will be righthow well does it perform?
I've noticed that the osmio4k autofocus doesn't work too well with that big of a beamwidth.

Nothing to do with the heat sink thermal dissipation qualities on a LNBF.
Physics 101... Thermal noise increases and the atmosphere attenuates and depolarizes during the day and especially during the summer months. Also may be experiencing a slight attenuation by particulates ((ie. smoke and ash drifting across the continent). SNR improves during the cold season.
Then what is the purpose of the heatsink? I read in some other forum that it's a useless item. Is that true?
yeah. so since you've tried it all so far. you get better signal with the scalar off but get adjacent sat interference. did you try for giggles a c-band scalar?
hey. it can't hurt, right? that's a hell of a small dish for c-band. kudo's for trying.
danristheman Dan, you are the resident expert in small dish C-band reception. I know you've not been around much lately, but do you have any advice for Johnny to help him tweak his 1.2m dish a bit more? |
