I recently setup a 1.2M minibud and having some strange signal quality issues I don't understand. I am able to get reasonable signal quality 50-60% on a lot of transponders however it will repeatedly bounce to 0% and then back to 50-60% (or whatever it was). At first I thought it might be a nearby tree but I had the same thing happen on another satellite with a completely clear line of sight. The dish or LNB isn't moving and I've swapped cables, receivers and LNBs but the same thing occurs. I completely understand the limitations of a MiniBUD but it doesn't make sense for it to repeatedly go from zero back to normal. Anyone have any ideas? Thanks for the help.
signal bouncing to zero?

The only time I have seen something similar to what you are describing - that is the signal going to zero is when there is a strong wind. But I am sure you would notice that because the dish would be bouncing in the wind. Make sure all fittings / screws are tight.
I live in BC and a 1.2m dish for Cband is touch and go. For KU it's awesome but for Cband... one day there the next day gone. Even on the strongest TPs from 91w it's unreliable. Cband on a small dish is totally dependent on your location. It just proved to me to be too aggravating and that's why I'm moving my old 7.5' fiberglass Cband dish from Dad's place to my place.( I finally was able to convince my wife) LOL.
Probably not what you wanted to hear, but a 4 foot dish just doesn't cut it, at my location.

I think you guys are correct that it relates to signal strenght. I tweaked the dish position which allowed me to get steady signal from some transponders and bouncing to zero on others. I'm toying with the idea of putting up a 6ft dish as thats about the biggest I have space for. My comfort level installing the dish, actuator etc is about zero so I'll have to give it some more thought.
In my experience, signal bouncing like that is due to adjacent satellite signals. It causes too much noise on the desired signal that the receiver can't lock. Even with my 8 footer, I still don't get the best quality on the high FEC muxes. You get get a lot with an 8 footer, but if you could, go bigger. My goal, one day, is to have a few 3.7m dishes that the cable companies use. Then I'll have no signal problems at all.
i was going to say Terrestrial interference or it could be a neighboring satellite fired up a transponder of the same frequency as the one you are trying to receive. 4 foot dish does not have narrow enough beamwidth to reject adjacent satellite interference especially since the past few years we are all digital...the noise gets too much and FEC cannot make up for it or receiver just can't lock it.
i always wondered how long the skyvision 6' dish and dsr 410 would last until the day somebody next to W5 fires up a strong transponder on one of the same frequencies as HITS.
