A little less analogue, and a lot more crap.

... bend over
I have been, most of the afternoon.

Can always fall back to the Global ADX plus switch, again.

Would you please be able to check if you have any WR75 flange LNB's in your box
No @moonbase , there is nothing interesting in the box, all LNBs are same, moreover, I am not completely sure they all in working condition.

Thank you for looking.
If you do find any other WR75 and with range 12.50 to 12.75 GHz it would be good for a test.

I have a collection of old WR75 flange Ku-Band LNB's amongst a pile of satellite junk accumulated over several decades. Before I disposed of them I thought it might be interesting to compare the performance with a few less ancient C120 LNB's. The only full band WR75 LNB's was a Swedish Microwave WDL Type E model with LOF of 9.75/10.600 GHz. This was the WR75 LNB used for the test.
I have attached a few pictures below of the hardware setup and a chart with data table presenting one section of the scan results. The scans were done using a Precision 2.0m dish.
Despite its age, the Swedish Microwave LNB held its own against various Invacom and Inverto C120 LNB's.
I am looking for the SMW WDL LNB using it in a testbed for the rejection of extremely strong interference from mobile communication base station. Ideally I would need two such LNBs for both polarizations, connecting them to the original SMW OMT which I already have. Do you still have this LNB?

It might be up to the job ?
The Global ADX I have here is one with a dual function switch, both up and down converter circuitry.
