As far as positioning of the Ku LNBF, the front of its actual feedhorn is somewhere near the back of the bulge of the built in scalar - if that makes sense. I found that after adjusting for best signal quality, my Ku LNBF has its front about 1/2 inch closer to the reflector than the opening of the C-Band LNBF. You'll have to experiment a bit. there's some Ku-band data transponders on 129W (SES15) and on 22W (SES4), that can be convenient for adjusting while the dish is pointing at low elevation.Not offended one bit. Great and detailed information. I ordered a GeoSat Pro LNB and bracket yesterday.
Treated myself to a nanoVNA while at it. If the standard LNB works out good, maybe a universal in the future to see what it can do.
You put it all in a way that's easy to grasp and understand. You know. You don't need 500HP to go to the store....but it's damned fun to know it's there.
Like mentioned I do have 22 KHz switches but also a couple of DISEqC multi port ones too.
The only fuzzy area right now is once I get geared to install the LNB is the difference in focal point in relationship to where the C Band feed throat currently is to grab the initial signal.
Do you think it would closely match, be equal to or further back?
I was not familiar with the nanoVNA. That sounds like a cool device! I have an old school spectrum analyzer, that is great for finding satellites but not for fine measurements. I also use an RTL-SDR dongle with ScanSDR, very useful for looking at details
