[TowerTalk] Rohn 45-g flat top section rotor loop protection

I did this with the rotor loop when I installed my crankup (which is a
flat top section). Not only do I have the coax, but also a Stepirr
control cable running through the 3/4 flex conduit.

So far is working well. I have only had the tower up since late July, so
too early to tell if any problems. I did make an effort to ensure that
water would not collect in the flex so as to prevent any icing problems.

The conduit is open, no connectors on the ends.

Three quarter inch liquid-tight conduit easily allows the RG-213 with PL-259 to pass making future replacement of the liquid-tight conduit if necessary, easy. I’m getting ready to try liquid-tight conduit as protection of the rotor loop and appreciate any observations or comments.
