A cheap LNB for Blockstream satellite? Has anyone here built their own setup for connecting with the Blockstream satellite network?

I'm still looking for a cheap low-noise block downconverter.


  PLL LNB (linear polarization) w/ &lt; = 200kHz LO stability


The ones I can find range from $100 -> $200..

Seems like 200kHz is not required, broader ranges are acceptable.
"L.O. Accuracy &amp; Stability Within +/-1.5MHz" seems to do the trick and they are considerably cheaper (~15$).
Grubles has written up a guide for how to set up a blockstream satellite node: https://medium.com/@notgrubles/building-your-own-bitcoin-satellite-node-6061d3c93e7. That should be helpful; it includes links to amazon where you can buy all of the materials required.
