I have a Directv slimline installation scheduled on 8/2/10. Here's the specifications. 1 HD DVR receiver and 1 HD receiver. If the Slimline dish is installed where my current Dish 1000.4 is, the approximate cable run is 125-150 feet. What extra equipment, if any, will be needed for this length of a cable run from the dish to the receivers? Please help.
