I have read that RG11, because of its thicker design, has a larger bend radius than RG6, thus making it unsuitable for residential use.
Ugggh! Stop reading that internet garbage! Unsuitable for residential use? Why, do you live in a tiny house? All cable has a minimum bend radius including 6 size cable.
Couplers? You mean F-81 barrel connectors like on wall plates? Yes they do have a loss but it's so minimal that it's not an issue.
What I have no use for are those 90 deg connectors. I believe the loss is more than a barrel, dunno. I just never liked them, maybe because a length of cable is so much cheaper.
