i just did a test tonight....i wanted to see which had the better tuner \ sensitivity.
my setup is a twin output LNB - on DISEQ motor, 1.2m dish.
for this test, one connection (via the motor) is going direct to Octagon SF8008 - the second connection going direct to the Edision MIO + 4K.
(in theory the second connection should be a better signal, as it is straight from lnb to receiver, no passing through the motor)
i drove my dish to 53e where my channels are weak atm - and found a channel, i then made it weaker but fudging my USALS to simulate a weak signal....i got it down to 3.2db - and was checking \ switching between both receivers as to which was maintaining picture stability - winner - Octagon SF8008.
see from photos, the Octagon held the signal \ picture (rather) much better than the Edision - the Edision was total breakup at 3.0db, the Octagon, maintained the image mostly, with an occasional pixelation - as ive been typing this, its hardly broken up at all.
So, all in all, between these two, the Octagon wins hands down, not only does it win for low SR tp's but also - has a more resilient \ solid tuner.
