[QUOTE="a33, post: 953252, member: 332642"] Well, I have one, but I am living in the Netherlands... :) After reading your testresult a memory came back to me, that I've read somewhere that it is better to have too small a monoblock on a bigger dish, than too wide a monoblock on a smaller dish (as Scubadan77 had originally -- sorry, I wrote his(her) name incorrectly above), even if the distance between the feedhorns is the same millimeters off of what it should be. I believe it had to do with the way the two feedhorns separate the signalbeams of the two satellites in the middle, and the signalbeams arriving more at the outsides of the feedhorns giving more signalstrength to the LNB. But I'm not quite sure if I recollect this correctly. By the way: the triple LNB for 19-23-28e, designed for a Triax64 (60cm) dish, gives (in Holland) even [U]better[/U] reception on a Triax78 (70cm) than on a Triax64, it seems. Though the aligning must be done with much much more precision than on a Triax64, as all the feedhorns are a bit out of focus; and you must find the best compromise between the three satellites. But, if you succeed in doing that, you get better results! For a Triax88 the triple LNB is worthless in the Netherlands, however. Greetz, A33 [/QUOTE]
