What is the difference between the “Round” 18″ dishes and the “Elliptical” 18″x24″ dishes?
The 18″ dish had a Dual LNB that looks at one satellite. The satellite is positioned at 101 degrees and sends all the main programming that is offered in the DirectTV packages. The 18×24″ dish has TWO Dual LNBs and is set up to see two satellites… the 101 degree and the 119. The 119 degree satellite sends additional programming such as the NASA channel, ParaTodos Spanish programming, other foreign language programming and HDTV channels. You could also use two Round 18″ dishes, one pointed at the 101 degree satellite and the other pointed at the 119 satellite to do the same as the Elliptical dish. You would connect the four cables from the two dishes to a multiswitch as explained in the Multiswitches FAQ section.
