Currently out of Contract I recently purchased a new 625 DVR receiver. I mounted a used 10 year old USED Dish Legacy dual/twin lnb antenna. The Antenna was completely disassembled when I received it from a friend. My question is: Is it possible to switch the lnb "heads" from left to right when mounting them in the yoke? Are the lnb's identical, or must they be placed in a respective position of left or right? I am only picking up sat 119. with my receiver. thanks.
