Maybe not, at least for Ku anyway. Time and the weather have been against me this weekend but I've spent a couple of hours trying to peak the Ku performance today and results are pretty much as expected albeit a little disappointing. Setup on Ku is an Inverto Black Pro on an Invacom ADF120 variable feed with 35m of CT125 and I'm comparing it against a 1.2m Gibertini with Inverto Black Ultra and 7m of CT125.
The first thing to notice is the supplied FS LNB bracket and arms don't place the LNB in the centre and looking at the middle of the dish. I've had to fabricate some clamps to hold the 24mm neck of the Invacom feed but the poor construction of the arms and mount had it looking well away from the centre. Not so easy to get it set correctly on this size dish so in the end I settled on placing a 913mm length of tube in the middle of the dish and adjusting four lengths of strings to get the high end of the tube equidistant from the dish rim. Once that was done the arms and bracket were persuaded into a position that's as close as I can get it to the centre as well as aiming at the reflector centre but I doubt I've optimised it.
Performance drops the further up Ku you go although there are humps and bumps along the way so the results aren't linear when compared to the 1.2m. At the bottom end the 2.4 is about 2-2.5dB better than the 1.2 Gibby, around 11700 it's about 1.5dB better and by the time you get to 12750 performance is between the same and 0.6dB better than the Gibby. I suspect that I could improve performance at the top end by sacrificing it at the low end so maybe I could find a compromise where it's 1.5dB better than the Gibertini.
Unfortunately I don't have a second LNB to test it against the 1.8m Precision so I can't compare the two without swapping LNBs from one to the other.
As an indication of what I've received on the 2.4FS I've done all the alignment on 5W and checked 7W.
5W 11059H is 10.6dB SNR, on 7W I've gained a couple of transponders over the Gibby and 11603H is 7.2dB SNR
