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.
