What Antenna Should I Use for Meshtastic?

For Meshtastic in the US, use an antenna tuned for the 902 to 928 MHz band with a connector that fits your radio, usually SMA. A gooseneck or whip of a few dBi is a solid all-around handheld choice, a longer whip suits a fixed home or relay radio, and a stubby trades some range for size. Antennas built for GMRS or ham bands won't work well.

Why does the frequency band matter?

An antenna works best at the frequencies it's built for. Meshtastic radios sold for the US run in the 902 to 928 MHz band, so the antenna needs to be tuned for that range. An antenna made for 2.4 GHz Wi-Fi, for the 433 MHz band, or for GMRS and ham handhelds may physically screw on, but it will waste much of your signal. A mismatched antenna can also reflect power back into the radio.

That's why the Foul Weather Whip V2, which is a good VHF and UHF antenna for ham, FRS, MURS and GMRS handhelds, isn't a Meshtastic antenna. One more rule worth following is to never power on a Meshtastic radio without an antenna attached, since transmitting into nothing can damage the radio.

What does antenna gain actually mean?

Gain doesn't add power. It reshapes where the signal goes. A low-gain antenna spreads energy in a fatter pattern that reaches up and down as well as out. A higher-gain antenna squeezes that pattern into a flatter disc that reaches farther toward the horizon and less above and below.

Higher gain helps when your radios are at roughly the same height across open ground, or when a fixed radio is mounted high and looking out over an area. It can hurt in hilly terrain, or when one radio is well above or below another, because the flatter pattern can miss them. For handhelds that move around, a modest gain antenna is usually the better compromise. Keep the antenna vertical too, since Meshtastic antennas are vertically polarized and two radios hear each other best when both antennas point the same way. Our guide on maximizing Meshtastic range covers height and placement, which matter more than the antenna for most people.

Whip, gooseneck or stubby?

Each style suits a different job.

Whip. A longer whip is a good choice for a radio that sits in one place, like a home node or relay. The V2 Mesh Whip is a base-loaded antenna for 902 to 928 MHz. The original Mesh Whip is an 11 inch BNC antenna centered on 906 MHz, and most Meshtastic radios need an adapter to use it.

Gooseneck. The Mesh Gooseneck is an SMA male antenna of about 3.7 dBi made for handhelds. It bends, so you can keep it vertical when the radio is clipped to a strap or lying in a bag.

Stubby. The Stubby is a short BNC antenna that covers 140, 440 and 900 MHz, so it works on Meshtastic with an adapter and on many dual-band handhelds with the right adapter too. A short antenna gives up some performance compared to a full-size one, but it's easier to carry and less likely to snag.

How do you get the connector right?

Connectors cause more confusion than anything else about antennas. Most Meshtastic radios with an external antenna use an SMA female port, which an SMA male antenna like the Mesh Gooseneck screws straight onto. To use a BNC antenna such as the Mesh Whip or The Stubby on one of those radios, you need the SMA Male to BNC Female adapter. Radios like Baofeng handhelds have the opposite port and use the SMA Female to BNC Female adapter instead.

The quick way to tell is to look into your radio's port. If there's a pin in the center, you need a female adapter. If there's a hole, you need a male adapter. Some radios, like the T-Deck Plus, use an internal antenna and have no port at all, so check before you buy.

Common questions

Will a bigger antenna always give me more range?

No. A well-matched antenna helps, but height and line of sight matter more. A modest antenna raised to an upstairs window often beats a large one at ground level.

Can I use my GMRS antenna for Meshtastic?

Generally no. GMRS antennas are tuned for frequencies around 462 to 467 MHz, far from the 902 to 928 MHz band Meshtastic uses in the US. Use an antenna built for the 900 MHz band.

Do adapters reduce performance?

A good adapter adds very little loss at these frequencies. The bigger risk is physical, since a long antenna on an adapter puts extra strain on the radio's port, so avoid bumping or bending it.

Is the antenna that came with my radio good enough?

It's enough to get started and test. If your range falls short after you've tried raising the radio, an upgraded antenna is a reasonable next step on radios with an external port.

For a handheld upgrade that fits most radios without an adapter, start with the Mesh Gooseneck.
