[QUOTE="satesco, post: 1066510, member: 297935"] Thank you [USER=175144]@Channel Hopper[/USER] for your intervention and suggestions :) Some years ago the interference was between 3500-3700 MHz.Unfortunately,they reached the last year at 3800 MHz,with the spread of 4G.What I notice on the spectrum, and because of that many frequencies are not detected, or the signal is very much attenuated.And to minimize the interference on the cable route,I use an external coaxial cable RG11 Triset-11 used for professional installations.The interference occurred with increasing the number of mobile cells near my antenna! Your suggestion would be good if I knew what that microwave protection fence looked like. If you have a picture of that fence, please post it so I can get an idea of what it looks like. [USER=191372]@scopus[/USER], You know,I used that Titanium,but unfortunately,it didn't really help.That's why I thought about resorting to an external filter,in the idea that I could manage to reduce the interference as much as possible. Of all the lnbs I've used, the one who helped me the most is an Taiwanese LNB,from the '90s, which has a filter on the housing. That's why it's a lot harder than LNBs in recent years.In those years, there were no economics on materials used for many electronic things.Everything was sturdy built. Here's how this lnb looks and spectrum with interference Best regards [/QUOTE]
