Re: Monoblock LNB question |
|
|
And whats more important, monoblock is working properly
only with dish 80 - 90 cm in size, and have fixed distance
and skew.
If you want to have good reception, it is better
to set together two seprate LNB's, so you can precisely
align distance beetwen LNB's and skew of each LNB.

|
| Into field [1.] input actual size of your dish [cm] eg. 90
|
| to [2.] put 0.5
|
| [3.] 0.3
|
| click on "Licz!"
|
| and you will get 100 cm dish after changing LNB.
|
| So, [90 cm + 0.3 dB] is the same as [100 cm + 0.5dB]
| In both cases EIRP = 45 [dBW]
