Multiband antenna loading coil printing guide: Stand the coil upright with the SO-239 hole at the bottom. Print two pole mounts at once while laying them down. The coil is wound with aluminum fence wire, using crimped terminals. A 5m / 16.5ft radiator will work on 60m, 40, 30, and 20m frequencies. Longer radiators tune lower frequencies. Required hardware: Three banana jacks (see link below) https://www.peconnectors.com/test-clips-hooks-plugs-jacks/hws16371/ or use M6 / 1/4 bolts with double nuts to hold antenna wires M3 screw, nut, and washers Crimp connectors: two with 3mm holes, four with 6mm holes One SO239 connector Four self-tapping screws (I used 3mm wood screws) Wire for the coil: I used aluminum fence wire Two pieces of wire: one to short turns, one to connect the start of the coil to the center pin of the SO239 Gator clip to short turns A piece of copper wire as ground bus The start of the winding is attached using a 3mm crimp connector and an M3 screw. Another 3mm crimp connector connects the M3 screw to the center pin of the coax connector inside. Self-tapping screws hold the coax connector in place. Ground connection uses a piece of tinned copper wire run between the ground banana jacks, held by two 6mm crimp connectors. The wire is run behind the coax connector for a good connection to ground. The end of the coil is terminated with a 6mm crimp connector, held by the radiator banana jack and shorting wire gator clip. Inspired by: https://www.thingiverse.com/thing:1725339 I printed this coil form but it needed many supports and was too large for my liking. This prints with minor supports and is less bulky.
