18" Dish: visually ID a single or dual lbnf?

[ahanif]

I have a 18" rca directv dish up on the roof - any way to tell standing on the ground if it is single or dual LBN without getting up on the roof?

Only if there are two wires coming from it. Then it is dual. Otherwise, you will have to loosen lnbf from the antenna, and visually inspect it.
