On masts with a very smooth surface, it may be better to use rubber band without a textile coating so that the tuner does not slide down.
For attaching the mount to your T1, remove the ground/counterpoise knurled nut (not the simple nut below the knurled nut!) on top of the T1 tuner, attach the 3d-printed mount, and fasten the ground/counterpoise knurled nut again. It is really important to not loosen the simple nut directly at the T1 enclosure, because you will have to open the enclosure to tighten it again.
