from western CT, with a side-mounted Titanium C1W-PLL with dielectric slab, on a 10-ft Winegard Quadstar:
AFN mux: stable reception at 7.2dB, plenty of margin
ANUVU mux (4132R30000): 4.7dB, and it requires 4.0 dB to lock, so not much margin.
I know I can also receive both with an 8ft dish, with the LNBF properly centered. Not sure of the DB levels
Note that the only unencrypted channel there is the MTN test card on 4132. AFN is fully encrypted, but if I remember correctly there was a time where AFN Sports was ITC for a while after the switch to HD back in 2018 or 2019
