Low cost PLL LNBs

Post by g4hjw » Sun Dec 01, 2019 9:38 pm

Evening all,

Apologies if someone else has already mentioned this, but I recently bought some cheap K band LNBs which have turned out to be PLL types (*3566E chip using a 25 MHz reference). The price is currently £2.36 each (no extra postage) from AliExpress:

Seems to work as well as any other that I have, but be warned or pleased that the LNB is encapsulated in a one piece plastic housing which will be destroyed if you try to gain access. I have pics, if necessary.

Bernie, G4HJW

I see that the stability spec implies an unlocked oscillator, but the pic shows a label with the same part number as the ones I received from a different source. So, some risk, but for that price perhaps worth it.
