Depends... If you are talking about a mast with the coax spiraled around
it like a coiled spring it'll work just fine.
Would I use it that way? Probably not, but I would use it for a rotator
loop if the need arose and I know it works quite well if installed
properly. OTOH, As I ground the coax at the top and bottom of the tower
which means I am going to need a connector in the cable at that point
anyway, I might just as well install a rotator loop using Davis
BuryFlex (TM) or another good, flexible cable. Three of the 4 loops are
28' while the one to the tri-bander is only about 18'. With 4 cables
bundled together I need all the flexibility I can get.
