    Bought a new HD flat screen TV. Currently have an SD R15/500 with 3-LNB 18" x 20" dish.

    Will I need a new dish to get an HD receiver?

    If I need a new dish will it need different/additional wiring?

    Yes you will need a new dish.

    Unless there is something odd with your setup your current wiring will be sufficient.

    The new dish will have a larger mounting plate though, so it can't go on the same mount/mast as the existing dish. That might result in needing some new or additional wiring. When the installer shows up, discuss the installation with him before he starts work, make sure you are both in agreement with what is to be done and how it will be done.

    Don't remove the old mounting plate from your roof - that results in risk for leaks.

    Don't try this, however;

    some of the advanced users here have kludged a 5LNB onto an old 18x20. My garage box is hooked up that way and it works fine, and the cool factor of having HD in the garage is considerable. (I don't get 110 and 119 and don't care)

    Just one of MANY fun things I have learned here. Keep in touch and read the informative and excellent posts here!!

    The best part is you just call directv for the upgrade and they will come out and install all the new equipment you need.
