Bandstacked C-Band conversion?

[Mr Tony]

OK trying to figure this out

Have a bandstacked C-Band LNB on my big dish. LNB LO are 5150 (V) and 5750 (H) which most of the receivers I have work fine

But the Quali-TV only allows LNB LO of 5150...wont allow 5750 (it has predetermined values and cant be changed) and want both polarities on it

I know on KU if you have a bandstacked LNB (10750 V or 13850) if your box wont allow 13850 you take the frequency and subtract it from 24600 (10750+13850). Does it work the same way for C-Band?

So if I want World Harvest TV at 4000 I take
5150+5750=10900 then subtract 4000 from it and get 6900?

LO 5150-4000 = 1150mhz on the RG6
LO 5750-4000 = 1750mhz on the RG6

I think you would just subtract the 600mhz difference between the bands to get 3400 for the opposite polarity of 4000mhz.

LO 5150-3400 = 1750mhz on the RG6

I'll try it tonight and see what happens

 

[Mr Tony]

yep that worked

I just drop 600 from the "normal" frequency so 4000 is now 3400 (example)

thanx

Cool, good to know it works with that receiver.
