Hi i just got my dual lnb today. I am looking to install it but want to make sure I know what im doing. Right now i have a single and its aimed at echo119 I know I will be looking to aim at both echo 100 and 119 once installed. I also picked up a cheap satellite finder to get sat strength. Any info would be nice before i try to install. Will I be reangling my dish or because im already aimed at 119 will these be suitable? thanks
