Short answer: Most likely no.

SignalStuff exists to fund HamStudy and ExamTools, so making custom antennas would take time away from developing the software. While we might make more money, it would pull us away from our primary goal of supporting these tools and the community.

Possible Exceptions

For large orders of 50 or more antennas that are similar to existing designs, we may be able to accommodate a custom order. These requests are handled case by case and depend on the availability and discretion of our current manufacturing partner (currently David, KD7VQT, unless that changed and we forgot to update this page). If you’re interested in a large custom order, feel free to reach out, and we’ll see if it’s possible… but no promises.

Frequency-Specific Notes

• Airband (~121 MHz):
  An airband antenna would need to be about 3 inches longer than the dual-band Signal Stick. While the SWR won’t be perfect, the dual-band version may still work better than a typical rubber duck antenna. We don’t have a way to pre-cut antennas for airband since we order everything pre-cut to save time.

• GMRS / MURS:
  The standard dual-band Signal Stick (19 inches) works well for GMRS and MURS, though not perfectly. Many users report good results. To fine-tune the antenna for these bands, you could trim it by 1.1 inches, though in practice, factors like how you hold the radio might have a greater impact than the trimming itself.
  For the single-band 440 MHz version, trimming 1/4 inch might improve GMRS performance, but the difference is often minimal.

Warranty Note

If you decide to cut the antenna, please be aware that modifications void the warranty. We won’t offer a replacement if cutting doesn’t improve performance, though we’ll still honor the warranty if the antenna breaks for unrelated reasons.

In short, while we don’t typically make custom antennas, large orders similar to existing designs may be possible. For individual needs, the Signal Stick can often perform well across various frequencies with minor adjustments.
