Cos of the 5g interference I get ...no? What lnb do I need for this range ?
You are getting 5G interference down in the 3400 - 3700 MHz range.
I dont see why this will interfere up in the 4500 to 4800 MHz range so you should not need a 5G filtering LNB.
There are also extended C-Band frequencies on 40.5W that are receivable at a UK location.
You need one of these Chinese bad boys pictured below or any alternative LNB that covers that range.
The LNB pictured below is the mini block WR229 flange type, it needs a cheepo Chinese horn pipe to bolt onto.
I got a box full of these Chinese bad boys for sale at huge wad, no bargains 'ere.
I think that there are also extended C-Band LNBF's available that you shove into a polo pipe or clamp directly into a feed holder.
