Your comment puzzles me a bit as it *is* a rotating tower. :-)
I have seen K0XG's product up close at Dayton in years past and helped
K0RH raise antennas on his 140' rotating tower made of a microwave tower
of some manufacture. K0XG had to customize the mounts a bit as I
recall. The inner rings surround and bolt to the tower legs. Agreed,
there is no added structure to eliminate the bit of twist that will
occur. Jim's tower has been up since 2000 and has probably survived
every type of Kansas weather except a direct tornado hit. He has plenty
of antennas on it.
Do you plan to use Phillistran or EHS for guys? I know Jim used
Phillistran on his.
