EXCLUSIVE

If "Duck Dynasty" network A&E feared advertisers would scatter like waterfowl after a shotgun blast because of Phil Robertson's anti-gay comments ... it's not happening.

A company called Skyjacker -- which builds truck suspensions -- tells us it stands solidly behind Phil and the show ... saying it's a matter of God and country -- it's a free country and Phil has a right to his opinions.

Company brass tells us it goes beyond the Constitution ... to the Creator: "We are a Christian- based company and actively share our faith so standing with Phil Robertson is an easy choice for us."

Robertson opened up a can of worms when he said homosexuality and bestiality were the same sin ... his church seems to back Phil up on that.
