[QUOTE="John, post: 1163074, member: 175005"] Regarding my personal battle with 5G interference - [USER=406637]@anto@[/USER] and myself have been doing nearly the same thing together but didn't know it :) .... I obtained a Titanium 5G RED C138 lnbf last week and first did a bench comparison test, ( not on a satellite) , between the C138 5G lnbf and a very very expensive Norsat 3200F-BPF-8 5G lnb . I was quite surprised, considering the large price difference, at the very similar performance plots when the two items were pointed directly at my headache 5G cell tower 300mtrs away which is kicking out two powerful 5G frequencies at the moment as indicated on the analyser grab. The Tit C138 response started to drop off from 3.885 GHz downwards on it's way to the band edge of the 5G 3.799GHz signal - the Norsat did not drop down in this same area and i found this to be a bit of a disadvantage . I'm a really big fan of Norsat lnb's but in this case where 5G is involved it was letting through just a little bit too much of 5G at the 3.799GHz area. With both items on the dish it was the same scenario. Due to the onslaught of 5G interference to my dedicated tunable Cband installation iv'e decided to construct an 'lnb changer' to my 2.2 PF antenna and incorporate a simpler Cband set-up comprising of a 5G Tit C138 lnbf, a separate 4.5~4.8GHz lnbf, a modified PF feed on an Inverto Ka/Ku lnbf, and at some stage to transfer my Extended Ku lnbf onto the new changer for the 2.2 Elite PF dish and possibly venture into Xband equipment onto the changer at some future stage. Here's a few pics relating to my words above ... 5G interference video, which also shows the destruction that happens further up the band to around the 4.068 GHz area - - [MEDIA=youtube]GDTn63qWldw[/MEDIA] .............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
