144 MHz Antenna 3D Models and STL Files

«144 MHz Antenna 3D Models and STL Files»

The designs fall into a few groups. Directional beams such as Yagi, Moxon and quad antennas use printed element holders and boom clamps to keep spacing consistent. Omnidirectional and ground-plane antennas rely on printed bases, radials supports and mast adapters, while dipoles and wire antennas often need only a center insulator or a feed-point block. Some entries are pure accessories: connector caps, insulators and small mounting brackets.

When choosing a model, read the dimensions first. Element length, spacing and boom diameter decide whether the printed part matches the tubing you already have, and the author's page usually states the frequency range and the hardware it was drawn around. Check how many separate parts the build needs, whether supports are required, and which material and print settings the author lists. Photos of real prints are the most useful signal, since thin walls and threads are where a print tends to differ from the render.

To widen the search, try the other names for the same band: 2 m, VHF, 145 MHz, amateur radio or ham radio. Related terms help too, such as boom, element, insulator, feed point, mast mount, radome and connector cap, since many parts are listed by function rather than by frequency. If you are adapting a design for another band, search for the mechanical part instead of the antenna type and scale the dimensions yourself.
