greatek lnb C band

[anto@]

greetings to all friends
I wanted to ask about an LNB C band
this lnb has 2 values of O.L. what is the reason for these 2 values?
1 for vertical tp
1 for horizontal tp
then we read that it starts from 3.6 ghz inside there is a filter that cuts the signals of the wimax?
thanks for replies

Correct. 1 LO setting for Vertical, the 2nd LO setting for Horizontal polarity. This type of LNBF is referred to as band stacked or single cable.

I thank you so much
so on the decoder or TBS I have to memorize 2 satellites (even if it is always the same satellite)
1 with O.L xxx
1 with O.L. yyy
in your opinion in this LNB is installed a filter x the vimax?
since it has a frequency range of 3.6-4.2?
I have installed on my system 2 lnb extended band from 3.7-4.8 but the signals below the 3.6 of the wimax enter the same and give me vision problems
Thanks again

Many STBs support this type of band stacking LNBF. Look in the STB's LNB configuration menu for OCS 5150/5750 type (One Cable Solution). The LNB voltage is typically fixed at 18Vdc

A Band Pass filtering LNBF attenuates all signals (both terrestrial and satellite) below and above the band pass frequency range.

Cannot comment on the filtering effectiveness of the 3.7-4.8GHz LNBF model that you show. In this case, the giftbox doesn't provide much information or specifications. Even if something was printed, the label or giftbox text often does not reflect the actual frequency range or specifications. They will print what you want them to print.

ok, maybe the question is wrong
I repeat, in your opinion, the model in the photo greatek spl 4600 has the filter that cuts the frequencies below 3600 ghz?

Thanks for the reply

The giftbox would suggest that it has terrestrial interference filtering. Connect a spectrum display to determine if the signals below 3700MHz are attenuated. Do you know the frequency and source of the interference that you are attempting to attenuate?

I haven't bought this lnb greatek yet, at the moment I'm just looking for information
on my system I currently have 2 lnb 3,7-4,8 ghz installed
unfortunately the signals of the wimax pass the same and they give me pronlemi of vision of the images
even if the signal is good

the wimax signals here from me soto from 3.4 to 3.6 ghz
in the photos you can clearly see the powerful signal of the wimax

Be safe over there. Watching kcra on cnn ch 7 fire took off now burning town.

We played golf at Winchester a few weeks ago. Yikes that is close.

kcra chopper leaving to Sacramento now. Be safe. I use Fire Duty App. Works really good for up to date info.
