Stargazer said:The signals that we are receiving right now are high power. The reason that we will need a different lnbf and a bigger dish for receiving 105 is that it is lower power. The lower the power the bigger the dish has to be to receive the same quality signal.
We have to start using lower power satellites because there is limited space for high power satellites. You have to keep them spaced apart enough to where they will not cause interference if they are using the same frequencies.
Different power satellites use different frequencies so the only solution to getting satellites closer together to allow one dish solutions such as the SuperDish is to use different frequencies.
http://www.ses-americom.com/media/2003/09_08_03.htmlAMC-15 will succeed AMC-2 and offer both circular polarization and high-power on the FSS Ku-band platform composed of 24 transponders of 36 MHz each, as well as 12 Ka-band spotbeams of 125 MHz each.

Stargazer said:I was thinking that they were going to use those higher frequency transponders for future internet services but thought they were going to be put at 121 instead of 105.
I know that you need a bigger dish to see more orbital slot locations in the sky seeing how the dishes get bigger the more slots that need to be picked up.
If one were needing to use a larger span of the dish for one type of signal then should the lnbf be focused more towards the center of the dish than the other lnbf's in which do not require as much of the reflector making the lnbf picking up the 105 slot more towards the center than the lnbf's for 110 and 119 in which only need to use part of the refector on one side to receive the signal?
Mike500 said:I have not heard what kind of H/V lnb Echostar plans to use for the 105/121 position. If it is stacked, it would be a NEW DishPro dedicated single lnb. If Dish plans only to use transponders dedicated to either the horizontal or vertical polarization component for all of it's offerings on SuperDish, which is the most likely and least expense alternative, then a DirecPC, any Primestar, or fta lnb will work.
