[TowerTalk] Cell Flex cable question

[Robert Harmon]

Have you used Cell Flex cable from Davis RF ?  Looking for feedback on this cable.  I am thinking
about replacing a 300 foot run of RG-213 from my shack to a 20M yagi with 1/2" Cell Flex.  .  It looks like it would 
give me approximately 1.8 db  less loss for a 300 foot run if I figured it out correctly. Much cheaper than hardline.
I am wondering if it is flexible enough to used in a rotator loop so I wouldn't need to use a section of more flexible 
cable for the loop ?
