5.  RF Cable Damage Due to Improper Handling

RF Coaxial cable damaged due to improper handling resulting in 1.7db loss in cable. Cable was pulled too tight around support bracket resulting in indentation in dielectric under outer jacket and cold flow of jacket where minimum bend radius was exceeded.
