Titanium C138/C238 - 5G filter C-band

I have already ordered the converters, they are already installed and they work great

It's just a pity that the band is cut off at the bottom

Hi guys, I´ve started a new toppic here.

FYI: coppied two reports above in this new toppic.

Ok,thanx

Das Innenleben würde mich interessieren, vom vorderen Teil.

I would be interested in the inner workings, from the front part.

Unfortunately, I didn't take any photos, the converters are already mounted on the antenna. But they have a waveguide inside and the probes are the same as in regular converters.

Vor einiger Zeit habe ich einen Hohlleiter-Vorsatz gebaut.

Allerdings fand ich bei den winterlichen Verhältnissen absolut keine Motivation dies einmal zu testen.

Meine Überlegungen dabei:

die Länge mindestens 1 Lambda der kleinsten Störfrequenz

der Durchmesser dass die Störfrequenzen nicht mehr passieren können.

Some time ago I built a waveguide attachment.

However, given the winter conditions, I found absolutely no motivation to test this.

My thoughts:

the length of at least 1 lambda of the smallest interference frequency

the diameter so that the interference frequencies can no longer pass through.

Hi guys,

down here are my four 5G LNBs, professional serie from Norsat 3800-4200. I bought them in spring 2023 after more than one year with 5G interferences on the full band. 5G towers grew up in front of my house since 2020, exacly three towers on the full azimuth travel. LNBs work very well, but during the last month I think new 5G mobile Freq. started from the Eastern tower and it's so close to 3800Mhz that the full band is disturbed. Quite good instead if I move to the centre or the west.

I think I will need an additional bandpass filter (the extreme series e-BPF). That's going to be new expensive decision and I don't know if the problem is going to be solved!!! I have to think about the weight of the feed system and absolutely solve this further problem.

I'll keep in touch...

Diese Investition liegt bei 4000 €. Ob sich das für die verbleibenden Kanäle dafür steht

Alternativ wäre auch die schaltbare Variante 3000-sBPF mit den Optionsvarianten 3800-4200, 3900-4200 und 4000-4200.

Allerding müßte man auch hier wissen, welche Frequenzen in der Region genehmigt wurden.

Das Hauptproblem liegt aber immer noch darin, dass man nicht weiß, wann wer welche Frequenz aufschaltet oder ausbaut.

Wenn die Störer, wie du geschrieben ahst, dann noch im Azimuth-Bereich liegen, ist dies besonders übel.

This investment is €4000. Whether this applies to the remaining channels

Alternatively, there would also be the switchable variant 3000-sBPF with the option variants 3800-4200, 3900-4200 and 4000-4200.

However, one would also have to know which frequencies have been approved in the region.

But the main problem is still that you don't know when who will switch on or expand which frequency.

If the disruptors, as you wrote, are still in the azimuth range, this is particularly bad.

In den USA geht ja richtig was ab in Sachen 5G. Lest auch die Kommentare.
Man braucht starke Filter und sehr grosse Satantennen, da alle Satelliten identische Frequenzbelegung haben und bei zu kleinem Antennendurchmesser einander stören. Zu klein sind alle Antennen unter 3.7 m.

There's really something going on in the USA when it comes to 5G. Also read the comments.

You need strong filters and very large satellite antennas, as all satellites have identical frequency assignments and will interfere with each other if the antenna diameter is too small. All antennas under 3.7 m are too narrow.
