[QUOTE="John, post: 1133653, member: 175005"] More or less done knocking this little mod up to fight the 5G virus, just needs the paintwork tidying up a bit and perhaps a final choice of Norsat Cband lnb after more testing. [COLOR=rgb(44, 130, 201)]Bare in mind that these components used in the re-build apart from the new external 5G filter, 4.5-4.8 GHz lnb have been molested many times over the years through experimentation so the install mod you see is not as pretty as it would if all brand new.[/COLOR] [COLOR=rgb(0, 0, 0)]Initial tests are good, the single 5G external filter is working good enough to stop the 'swamping' effect caused to the feed / program frequencies at various satellite positions around the 3.7GHz area. The 4.5 to 4.8GHz lnb range didn't need a filter as the 5G cell interference around my location didn't cause any problems... at this stage a cheap 4.5 to 4.8GHz is good enough. The AV-Comm OMT is advertised as 3.4 to 4.2 GHz operation range but after doing a non-professional but carefully set up bench test using a 4.8GHz signal source into the OMT + lnb's the captured readings on the Promax were identical from both ports which surprised me as i was expecting the side port to show a different reading - off air signals from 65West 4.5-4.8GHz signals showed to be as good if not a bit better than the previous set-up not using the OMT. A few more nuts and bolts to add onto the 5G filter ends & bit more testing to do but so far worth the effort. ================================================================================================================== [ATTACH type="full" alt="12volt drive motor.jpg"]144264[/ATTACH][ATTACH type="full" alt="0-22K switch for lnb band switching .jpg"]144266[/ATTACH][ATTACH type="full" alt="4.2-4.8 GHz Lnb.JPG"]144267[/ATTACH][ATTACH type="full" alt="4.2-4.8 GHz Lnb.JPG"]144267[/ATTACH][ATTACH type="full" alt="AV-Comm 3.4-4.8 GHz V-H-L-R pol OMT Build.jpg.reduced..jpg"]144268[/ATTACH][ATTACH type="full" alt="5G C-band filter-.jpg"]144269[/ATTACH][/COLOR] [/QUOTE]
