Yes, it would be ... I have considered trying to get 25'
(about three turns) of the 1.25" Nycoil material and running
two or three pieces of LM400 or equivalent through it as a
rotor loop. The bottom would be attached to the tower and
the top attached to the boom of the lowest beam ... if the
coil represented three turns "at rest" I would add an extra
"half turn" when it was attached. The real problem is
weight ... as I recall, the empty conduit weighed about a
pound a foot.
If someone wanted to experiment with a "coiled" conduit for
a crank up tower or as a rotor loop ... it might be worth
looking at non-metallic "Sealtite." I believe the Sealtite
line is available in sizes up to a couple inches in diameter.
