What is the appropriate way to prevent interference on the LNB C band due to 5G mobile towers?

Options are:

1. Use an LNB(F) with internal circuitry 5G filtering.
2. Insert an in-line anti 5G bandpass filter between the feedhorn and the LNB(F).
3. Erect a wire mesh structure at the relevant location on the dish site to prevent the 5G getting through.

Most people go for option 1 or 2.

To solve the problem I also purchased 2 Titanium lnb C band filter 5 G and I am fully satisfied with them, they have a slightly higher price but it is worth spending more to receive more

The Titanium work quite well for a consumer LNB, but definitely have their limitations in filtering ability. The Norsat 3000-BPF series are leaps and bounds ahead for both cutoff and stability, but they command an extremely premium price in comparison. Depending on how severe your 5G interference is, there is sometimes the need to use both a filtered LNB and an external bandpass filter together. I have a receive farm located right beside a 5G transmission tower and it was a nightmare to filter out the noise!
