By the way I have wrapped some foam insulaion around the LNB body and the drift is much slower so easier to follow any SSB drift.
Mine is actually Horizontal so Mini Tiouner feeds port 1 in my case on LNB with 12v.
I have an ebay DC -DC up converter to feed a bias T.
The output of this is actually switched so I can have 12V or 18V out.
Normally 18V is output and this feeds a SDR for trveiving SSB.
Its quite stable but does drift over time.
I think your idea of an insulating wrap is a good one and is what I will do next week.
Drift is however very slow and easily rectified with a few mouse clicks.
Meanwhile I am also working on the transmit side but that will take a while.
As you have probably found it is also best to leave power to the LNB ON.
I have low drift but the worst drift is from some transmitters on SSB and then the responding station also drifting and not netted.
I too have all this learning curve to look forward to.
Currently constructing a higher power Amp but struggling to source reasonably priced 90 degree hybrid combiners
hear and see you soon on SSB and DATV

I have one here, but haven't had time to try it yet. Be careful, because there is an identical looking and named variant that is cheaper and is not PLL.
I align the dish on bbc arabic
then on Duabi one 12130v 27500 3/4 its a weaker transponder but if you can get a lock on there to have it bang on position
i find my 1m dish is very sensitive.
one port is fed 12v via bias T for vert for NB on my sdrplay.
The 2nd port fed from my minitoiune thats has got a 12/18v switchable lnb supply feed( added it myself )
3 port goes to my sat receiver for Normal Tv
Im receiving ATV signals down to 66ks got a good signal of G7JTT tonight at 66ks
The exception to this is with Quattro LNB's where each port is one of the following: Hi V, Low V, Hi H, Low H. These do not use tone or voltage switching.
Port 2 has a LO of 10.057529 with a stabiliuty of 2PPM
seems to work very well.
