A measurement with my Spectrum Analyzer (with tracking generator) showed that the insertion loss is around 5dB.

The F plug is still not here. | A measurement with my Spectrum Analyzer (with tracking generator) showed that the insertion loss is around 5dB.

1 Scope
The new Es'HailSat from Quatar has received wide attention. Let's start to play with it. The first step is to receive it's signal.
By coincidence I purchased an LNB with a LO frequency of 9 GHz some years ago, while never using it. Now the occasion has come to really use it. Yet, some more components are missing:
- A DC injector
- A receiver component
- A satellite dish

I have one from Dieter DL2KBH:
3.2 Injector
This component needs to be home built.
And here it is:
