DirecTV Eyes SES Service at 105 Degrees

Wasn't SES going to have some differences in which would prevent it from having interference with 101 and 110 DBS satellites such as left-hand circular polarization.

If this were the case then the lnbf's we currently have that we use on DirecTv and Dish Network would not work unless you had a dual reflector (like the torodial dishes for picking up multiple orbitatal locations as a one dish soution) where you have one reflector in front of the other one. When the signal hits the reflector it changes direction from right to left or from left to right.
 
I wish the DBSs would quit trying to co-occupy the same slots. This forces them to have to use more slots to carry a certain quanity of transponders. Hence we have to have goofy 1/2/3 satellite capable dishes, or even more than one dish.

If D* had all of the 119 TP, E* the 110, and V* the 61.5 then that would have made life easier.
 

I don't think D* is deliberately trying to occupy the same slots as E*. They are just desperate for bandwidth anywhere they can get it (the closer to the core slots the better) and SES is willing to offer them some transponders at 105.

By the way, E* is using more than a single orbital slot's worth of transponders, even taking duplication into account... So totally occupying just one slot would still leave them needing more bandwidth....

Don't blame E* and D* for this. Blame the FCC....


I think this is interesting because it means that E* did not lease ALL the transponders at 105....

Regarding the polarization question, AMC-2 currently uses linear polarization. AMC-15 (the replacement) uses circular polarization.

All you have to do to provide more space to fit in the LNBFs (for tighter orbital spacing) is move the focal point(s) of the reflector further out. [not addressing adjacent bird interference here, just the physical LNB interference....] Make the reflector "flatter" and the support arm longer....
 
DirecTV currently uses three orbital locations as it is, 101, 110, 119 that are close together and by adding 105 to the mix that would make them four, the same as Dish Network, that are close together in which can have a one dish solution (105, 110, 119, 121). Dish Network still has more bandwidth available at their four orbital locations that could have a one dish solution, then Dish Network has 61.5, 148, etc. to boot.
 
Stargazer,

The title is a bit misleading. DirecTV is opposed to SES Americom providing service at the 105 slot because of possible interference. DirecTV doesn't want to use 105 themselves; DirecTV doesn't want anyone to use 105.
 
DirecTV's petition to the FCC, which discusses their objections to the use of 105.5 degrees, can be found right here (PDF document). It's a good read.
