well, I was going to give up on the 621. I thought I would give it one last try. I enjoy experimenting in this hobby but this thing has got the best of me.
With the lnbf on the dish pointed at g10r ku 11800V I got on a step ladder and took a screwdriver and removed the ku part. I removed the three screws and removed the o-ring.
With a tv out back next to the dish I had the on screen signal quality meter up on the pansat 9200Hd.
I skewed the ku part a little clockwise and held the ku lnb part in the hole and watched the singal - It went up from 70 to 84! Wow.
I already had c-band skew peaked (keep in mind) on the scrambled outdoor channel.
Now as it stands the ku and c-band probes are not lined up like they were.
Theoretically the skew should be wrong one way or the other. C or ku should be wrong.
I left the focal point as it was and skew of the c-band (main lnbf body)alone since any movement dropped the c-band signal quality.
Now-I have somewhat acceptable ku across the arc and pbs ku amc-3 is coming in at 58% quality (12138V 30000). Before I had virtually no signal on this one.
SBS-6 onn went up to 82% from 70%.
I now have isolation between H and V tp's when doing a blind scan.
Before, the strong ones would scan both polarities and no amount of skew would stop it without losing signal.
I am leaving it alone but am still going to replace it with a corotor.
I am happy it is working for now.
This has been a strange lnbf. My homemade frankenstein lnbf as one of the members called it-LOL, still gets much stronger ku on my 7.5' sami mesh.
Same exact antenna as my 10' except it is a 7.5'. Both antennas are fairly new.
No additional azimuth or elevation changes peak the signal from where it is now. I am confident I am tracking the arc.
