Squid pole top spike

thingiverse

Radio enthusiasts employ squid poles to support antennas during portable operation. Heavy-duty squid poles, like the Haverford model, feature a spherical tip. Attaching an antenna to this spherical tip can be tricky, but it is precisely what you need to secure the center of a dipole antenna. The end of the attachment piece fits snugly over the spherical tip and provides a threaded spike for easy attachment. Unfortunately, I discovered that the original threaded spike was not strong enough, so I opted for an M6 x 25mm nylon bolt and nut for improved durability.
