Contains 2 guy plates for guying mast at two levels.
Diameter of top plate & bushing: 40mm
Diameter of bottom plate & bushing: 50mm
Guy lines can be affixed in 3 directions (120°). The whole mast can be rotated inside the guy plates, i.e. the antenna can be turned by hand from the ground. You can also mount a rotator at the bottom of the mast (For example, a KR-450 or KR-650 will easily turn the whole mast including the Spiderbeam).
