Antenna guy plate

thingiverse

This plate is crafted to fit snugly over an extendable fiberglass antenna pole - often fashioned from a 'fishing' pole - and rest securely on each segment. You can then attach guy ropes to keep the pole upright and feed the antenna wire through the other holes. You'll need to measure out the segments of your pole to figure out the perfect size for the center hole; I've also included a FreeCAD file in case you want to personalize or ensure that the hole is precisely tailored to your application.
