But I am quite confident that that sac 120 is worst than the triax110.
As we know from above posts, S.A.C. 1.2m, in reality only 110cm dish. Secondly, did you check it for warpage? Was LNB located in the right location? Was LNB's illumination angle fits to dish opening angle? So, that easily could be hardware problem applied particularly to your piece of hardware.
Anyone knows how CM 120 compares with triax 110 in terms of signal?
When we compare dishes, we can speak about their sizes, quality of paint, weight, material used, but not performance. Performance could be measured only of satellite systems: antenna, LNB, cables, connectors, switches, receivers.
Two different sat systems: same size dishes, both in perfect condition, both have well fitted LNBs, same cabling, same receiver will give you about the same performance. If one of those systems, has bigger dish than it's performance will be better. Physics.
So, answering to your question: system with CM120 dish will perform better than another system with Triax110, and this difference will be approximately 18% better.
CM120 is nice dish, very durable, dependable, precisely made, always keeps it's shape, can sustain heavy weather conditions..... but it is only 120cm dish and can not perform much better than even no-name dish which has same size, but has perfect shape and all other parameters are also perfect. Another issue is that some dishes, after some time or windy conditions change their shapes, than system's performance goes down.
I wish to have my own CM120, cuz it is good 120cm dish. ;)
It doesn't look cheap to upgrade with brand new components.
Did you expect to get everything for free?
Look in local second-hand market, sometimes there are really good deals available.
@mariust5 I am sorry as well.... sometimes, when it is full moon (oops, it was yesterday) I write too much
