[TowerTalk] Coax, solid center

[Shannon Boal]

Greetings, Tower Talkians
    I am installing a beam or two, and have only coax with solid center.
(Belden 9913, etc.) Has any one used this successfully for the flexing part?
Maybe a large, carefully supported loop? I have heard of using 1/2 "
corrugated hardline, so maybe it can hold up without breaking where the mast
rotates. I would like to hear of anyone's experience here.
                         Thanks in advance
