Interference problems can be difficult to track down, and even more difficult to solve. For the avoidance of doubt: whatever we do to fix the issue, we will not eliminate the interfering signal, we’re only trying to mitigate its disturbing influence.

 

Rule of thumb: the more urban and/or population dense the area, the higher the likelihood of (unpredictable) interference.  Moreover, a clean, interference free spectrum today is not a guarantee for tomorrow’s situation.

 

What’s we can do

 

Mangosat performs a professional and very thorough interference inspection. Other than trial and error, this is a highly technical operation, and only a few of our field engineers are capable of performing it. Why? Because it requires a lot of theoretical knowledge, practical experience, systematic analyzing (patience) and beyond standard (rather expensive) measurement equipment such as probes and a spectrum analyzer supporting the required functionality. There’s simply no trick (one can learn without understanding what you’re doing) that can possibly bypass the necessary steps in the process.

 

If done properly, such an exercise can take more than a day because you want to observe the behaviour of the frequency spectrum under test for at least 24h

 

The objective of this more scientific approach is to understand how disturbing signals interfere with our wanted signals, where and how it enters the system and how we can mitigate the situation. Example: If interference is caused by reflection and we understand the basic facts, moving the antenna 1 m either way can already give good results and there’s no further need for iffy constructions. Also calculated shielding in specific places around the antenna or feedhorn can do the magic.

 

Conclusion: before thinking about any solution, we first want to have the problem clearly defined. Afterall, understanding our problem is 50% of the solution. Unfortunately, positive results can never be guaranteed.
