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!
