Upgrade your antenna to this flexible whip design.
Improves performance, measured SWR of 1.3 compared with the stock stubby antenna at an SWR of 3.5.
SWR is a measure of transmission efficiency, how much power from the LoRa radio makes it out into the world via the antenna.
- SWR 1.3 = 98% efficient
- SWR 3.5 = 69% efficient
Connection is SMA Male.

This antenna is a powerhouse. The 10 dBi whip from Muzi Works provided a clear improvement in range and signal quality over standard whips I’ve tested. It’s lightweight, sturdy, and performs beautifully in both open and obstructed environments. You can tell it’s been tuned with precision — great signal strength, quick acquisition, and consistent reliability. Excellent design and finish as well.

Threw this antenna on a nano VNA to see where it was tuned not only was it tuned for the 915MHz band like advertised but also at the stated SWR of 1.3, very efficient antenna and getting some real GPS range from it
Significant upgrade from the default stub antenna that ships with Heltec SBCs.
These whip antennas are pretty good for the price. I tested all four that I bought with a Nano VNA-H4, and the SWR was consistent between 1.1 and 1.3, depending on the frequency. For perspective, the antennas that came with two major suppliers of Meshtastic gear had an SWR of 1.6 and 1.8, respectively, for their “stock” antennas.
My wife and I will typically hike together but sometimes, especially with a larger group or when backpacking, end up outside of yelling distance. I discovered Meshtastic devices as a lightweight and less-expensive (and potentially more reliable?) alternative to satellite comm devices so decided to give it a shot. The stubby antenna that came with the Heltec v3 was pretty much garbage, so I decided to give this one a shot. Yesterday, while meeting up with her for a PCT section hike resupply, I was able to reach her when she was about 2 miles away as the crow flies - and that was with tons of trees in the way (LongSlow preset). I'm impressed :-)
