titanium C138

[dreambox1959]

A few months ago, I bought a Titanium C138 LNB;
I installed it on my dish this afternoon.But during testing, I couldn't find any channels at all!
I checked the dielectric plate and the connectors...
I ran a full scan and found a few transponders on 8° West, but not all of them!
The LNB packaging says: 3800–4200 MHz.With the 5G filter, I'm losing 400 MHz!
I used to use a cheap Chinese LNB (3400–4200 MHz range) without any issues.
Is there a good C-band LNB (PLL) that covers the full range, or at least the 3600–4200 MHz range?

If you bought this LNB, you should have known that it cuts off frequencies below 3800 MHz; it is doing its job correctly.
If there is no 5G in your area, then any LNB will work.
But if there is 5G around you, that is the one you have to use—you have no alternative.

That is what I did with two identical LNBs.
