at the moment I have solved the 5 g problem with the 5G maximun filter lnb
I bought them on Ali....
they filter down to 3.7 and that's fine with me for now
I was completely blind to all of the C-band before

there are 3 models 1 out 2 out 4 outs I don't like the 4 out because it has 2 O.L in my opinion 1 O.L for polarity and consequently difficult to manage with a decoder or pciE card I got the 1 out model

I just thought to share this interesting and straight-forward explanation of the problem.

Here in the West of England, all signals below 3.715Ghz are covered in 5G interference wherever I point the dish.

Sounds like your surrounded with the things Simon - i'm pretty sure looking at web data that i just have the one 5G tower about a 1/4 mile away but the thing is more or less in direct line of sight when the Cband dish is pointed from about 40.5°W to 71°W. At the moment anything from 40.5°W going Eastwards is escaping the problem but no doubt it will change . I'm trialing double 5G filtering at the moment using an AliEx External 5G filter coupled onto cheap Chinese 5G lnb's but i'm still struggling with a 5G signal at 3.685GHz even through 2 x filters which i think one of the reasons is that the stop band of the filters is just not quite in the right place for want of a better description and it's letting a chunk of 3.685GHz through the net. I could use a filter that does cover the unwanted frequency but at the cost of limiting the receive fx band to 3.8GHz upwards. Myself and moonbase were saying recently that the present channel structure frequencies will be shunted further up band if possible and possibly also into the 4.5-4.8GHz part of the band if uplink / downlink equipment and the rest will allow it.

This LNB might be interesting. It has the extended frequency range with an additional 4.5 - 4.8 Ghz and a 'TI' filter not '5G' ... Unfortunately only available in India

forget these lnbs
I have 3 and all three suffer from the 5G signal
I replaced them because I couldn't see any channels
the tbs stored them the tp but they were not visible
I memorized the tp at 40 west above 4.5 ghz
with strong signal but no picture

I have 3 for sale if anyone is interested
and maybe even 4
get it from india

That earlier link from satfaca (Tracksat) appears to be peddling similar items under the 'SOLID' rebrand.

what has been linked does indeed allow 5G to pass
that of Satfaca is another model with a 5 G filter

More than one product, pure promotion.

Prices are no higher than 25Euros

attention DO NOT BUY this type of LNB which is bad the 5G signals on the 3600 pass and destroy the signal above the 3700

tested today BAD product

surely i will send bad report to this bad quality product
this way they will stop selling products that can't keep their promises
and if you do it too, no one will buy this product anymore
I am very angry

How is this lnb? Have you tested it?
What is the frequency range it operates in?
How is the signal reception?
Do you suggest we buy it?
Can you share the product link?

If you pay by credit card, purchase three/four plus shipping, and it comes to over 100 Euros, you could get a refund through their complaints procedure.

one output maximun is better than Bwey (red)
5 G signals are filtered better, even if some noise is seen

Can you provide further details as to what difference the filter really makes? Do you have any visual documentation of the spectrum?
I would really like to be certain of the benefit before I get into such investment. I am afraid that with proximity of the 5G transmitters & the interference I get there is no magic device that could help.

Iv'e got a metal railing one across the road 10mtrs away but it's got big holes in it :D .....BUT, the theory is right. If i look at 70°West on the 2.2PF with the narrow beamwidth and with the low inclination i get some degree of 5G showing on the Promax - I think my beamwidth/boresight is just skimming over the 5G emitted radiation from the tower a 1/4 mile away - IF i lower the dish a fraction, loosing signal from the satellite, it effectively brings my dish beamwidth down to point more directly at the tower instead of just over the top of it and the 5G interference shown on the promax display almost doubles in strength. Hmmmmmm

putting the nb with 5 G filter and then also inserting the separate 5 G filter you get a doubling of the filter value
however I must also say that if 5G ends at 3800 these products are useless because they filter at 3700
