[QUOTE="Captain Jack, post: 986274, member: 243342"] Right - it's up! Looks far more tidy than Laminas bracketry - might need to rework that. The declination jack point is a little low so will move that to the top bar ... at some point. LNB changer will be fitted in due course. Already fitted the bracing arms (same arrangement as [USER=175005]@John[/USER]'s) to take the extra weight. [ATTACH=full]97886[/ATTACH] [ATTACH=full]97887[/ATTACH] [ATTACH=full]97888[/ATTACH] So, what's it like compared to the Laminas... 1) It's HEAVIER - much heavier. Swimbo helped me carry the CM from the garage to garden and we stopped 4 times. Carrying the Laminas to the garage took one attempt... 2) It's sturdier than Laminas. I took the LNB changer off the Laminas because it was becoming warped with the weight on, even with reinforcement arms. But CM is heavier... so which do you take? 3) Obviously can't fit C band LNBs side by side like I could with the Laminas.... 4) Checking signal quality levels across the arc showed that it's slightly lower than what I had with the Laminas (about 0.5dB lower). That said, I haven't spent much time optimising the signal and only tried the GI and IBU LNBs (IBU lost big time). I have a CM feedhorn that I want to try but don't really have many C120 LNBs to play with. Will play some more soon. In the meantime, if someone can suggest a nice C120 LNB that goes well with the CM feedhorn on this dish, I am all ears. At the moment, because of lighter weight, ability to use it with multiple LNBs without sawing off the arms (LNB ones, that is) and slightly higher signal - the Laminas wins. It's a very, very good dish that should not be underestimated. [/QUOTE]
