Hi guys. I just purchased a DPP TWIN LNB Pro Plus Dish Network DPPTWIN 110 119 500. I will be connecting it to my 322 receiver that I will take from my house and use for our RV trips. I was told that I wouldn't use the one connection on the right. Do I need a switch or can I run a single coax from one of the 2 coax connections on the left of the LNB to my receiver? I will be running it to just one TV. Thanks alot for any help.
