I modified the C band lnb I bought from Turkmenistan in 2012 and added the KU band lnb.

KU band lnb Inverto Black Pro flanged lnb, which was a gift to me from a dear friend
First I tried to shift the lnb slightly to the left from the middle of the C band (Lnb to the left when viewed from the rear, to the right when viewed from the front)
When I looked inside the C band lnb from the front, I tried to mount the KU band lnb on the right side so that the KU band lnb would not interfere with the signal reception due to the equipment providing the signal. Left.

Back marking of C band lnb done




Red line center point on the right


Since the signal receiving mouth width of KU band flange lnb is 1.8 cm, mounting holes are added to the sides to the 1.8 cm wide signal receiving hole in the middle.




Attached with metric 4 x 10 mounting bolts


RESULT










Results: Sorry, signal loss in KU band :(
But normal tv channels are watched :)


TRT Package 7 degrees east





C band broadcast from 10 degrees east
(Normally, I receive the broadcast that requires license plate. When plate is lnb in C band, the signal is received higher in R and L broadcasts. But does it affect the reception of plated C band, KU band signal? I will see :))

What should be really interesting to see is if the dielectric plate when is inserted in this custom combo LNB will also convert Ku band to circular, useful for 36E?
