I really liked the Dipole / Inverted V Balun Antenna Centerpiece from kaliway, but it was a bit of an overkill for a FT140-43, so here's a redesign.
Features:
- smaller, thinner and more compact (should be less than 5-6 hours to print)
- thinner thread for the lid
- center mount to secure the ferrite core, with 3 holes for zip ties
- M4 screws for the dipole wire
- SO-239 connector
- reinforced holes for the screws
more holes in the lateral arms for extra reinforcement or a dual/multi-band dipole
Due to the smaller size and restricted space, you might want to use a bifilar winding instead of the traditional "coax over ferrite" wrapping.Can be printed with no supports.
