My curent setup is a dual LNB antenna feeding a standard receiver and an R10 DirecTiVo. The installer that came out to give me the R10 put in what he called a 2x3 splitter. I didn't think to visually look at it to see what it really is. I just called the customer retention number and got the woman to give me an additional $150 credit if I buy a HR10-250. She said I could buy one from a store and would qualify for the credit and the $200 standard rebate since I wanted to install it myself. My plan is to retire the old receiver and end up with 2 DirecTiVo units. Looking at BestBuy's web site, it looks like there is no antenna included with the HR10-250 package. I'm just trying to figure out what all I'd have to buy in order to get it to work. Will I need a triple LNB antenna and an additional splitter to provide the 4 inputs to my 2 DirecTiVo units? BTW, I already have an antenna in my attic that provides a beautiful signal for HD reception.
