No free channels on 110 and 119 other than dish commercials etc. The one on 103 is your best bet, just need a bigger dish if you are getting rain fade. There is also a cozi on 105 C-band.
Maybe you can receive one of the US stations that carries cozi OTA?
Steve Gyurki said in the other post for Cozi :
If you look at DishNet 110 with a circular LNB you will notice that FETV on transponder 10 is in free preview (it has been for a long time). It has all of the COZI programming on it during the day. A lot easier than getting 103 with a linear LNB.
FETV is also on CBAND @ 99W
Just guessing, that is probably where dishnetwork is grabbing it from.
And yes FETV does show Cozi quite a bit.
Cozi itself is also on CBAND at 105W, and as pointed out Ku at 103W
If 103W Ku is fading out on you, I suspect you may be better off with a better antenna.
My old Primestar antenna does pretty well with it. I think it is close to what a Starchoice
84E would be.
