Hello,
I have modified a Gilat AN 8002 LNB so that all three bands (A, B and C) in the KA band can be switched with one LNB. With the polar converter presented here it is now possible to receive all four polarizations H, V, LHCP and RHCP as well as band A-B-C with one device. The annoying replacement or a complex LNB changer is eliminated. Unfortunately, I am unable to reach Band D with this LNB. Currently, I lose about 2 dB in band C above 20900 MHz.
I will try to modify the filter to compensate for these losses.
Everything is controlled with the POLOLU controller.
best regards dreamsat
