LNB with Waveguide input for QO-100


Here is an LNB with waveguide input for QO-100 or other measurement purposes.
It is a original PCB from the Octagon Single LNB, a PLL LNB stabilized with quartz. 
I removed the crystal and installed a better one with TC 2ppm, so that 10GHz signals 
can then be heard at 432.500 MHz.
Note: Original PLL LNBs have built-in  crystals with TCppm between 10 and 20ppm , for DVB-S is not needed more precisely !!!
