Hi guys I have directv with 3lnb swm at my house. I just acquired a slimline dish with the 5 lnb from my dad. I wanna set this up as my tailgate dish how hard will this be and what do I need to do as far as set up goes. I have the base and power source. Should I buy a 3 lnb like I have at home would this make things easier? Any help is appreciated
