I have used a Carry Out for about eight years. It has worked well for me. It does not receive HD signals.
When I'm worried about security I lock it to my coach or a tree using a cable designed to secure a motorcycle. My Carry Out has a metal tab designed for a security lock.
I read an account online where a camper put a doorknob security device on his antenna. Early in the morning the doorknob alarm went off. He hurried outside to find someone fiddling with his antenna. The guy claimed that he thought it was a barbeque and that he wanted to look at it.
Safe travels. JD
