In Japan, we must use authorized antennas.

You can take a look at the products listed in the following link to see if they meet your requirements.

I wonder where I can buy spring antenna, patch antenna and colinear antenna.

You can search for the antenna you want on the bazaar website to see if you can find one that meets your requirements.Here is the official website link of Bazaar.

I found the antenna Model.
Again, I want to ask same question.

Where can I buy this model of antenna?

Hi there ,

SO , is there a specific reason? the test document says all the specs were performed using the Highest gain ant ? the 8.9db or something?
I see this is close from digikey…

50Ohm, 10watts, 2.6db, 928mhz FPC

Thank you for your comment.

Addittionally, Im glad if seeed studio add below anntenna as authorized antenna.

Let me ask again.
Where can I buy M01-0401030R0A and V1194-145-A-01 antenna?

By the way, Where can I buy V1194-145-A-01 ?

seems to be “LoRa Fiberglass Antenna Kit For Helium; 902-928MHz; 5.8dBi; 800mm; RF Explorer RFELA-3/58X”, however this antenna gain is 5.8dBi

uecken · October 7, 2025, 3:38am

However, I noticed that EIRP must be less than 16dBm.

For most people, using a 3dBi antenna with a transmit power setting of 13dBm is the most common and practical option.
Therefore, if you could add the following three antennas to your Authorized Antennas, it would be extremely helpful as it would make Meshtastic devices much easier to use.

I would like many people to use Meshtastic, but the antenna issue has not been resolved.

I think Antenna 1 or 2 would be ideal as a compact antenna for carrying around, and Antenna 3 would be ideal as an antenna for a fixed station.

Would there be an additional charge for a certified antenna?

If there is a charge, I would be happy to consider paying that.

By the way, is there a restriction that antennas must be certified overseas? Or is this a restriction that only applies to Japan?

Hi there,

I would agree, The antenna situ is the weak link.
We could use some clearer more concise info on ALL of it

Anyone able to fill in the info ?

LoRa SX1262 Antenna Spec Checklist

1. Frequency Band

868 MHz (EU)
915 MHz (US / AU)
433 MHz (legacy / local law)
(select the band you need)

2. Impedance

50 Ω (standard for SX1262 RF front end)

3. VSWR

≤ 2:1 across the band (≤ 1.5:1 preferred)

4. Gain

2–3 dBi (typical omnidirectional)
Higher gain (≥ 5 dBi) only if directional coverage is intended

5. Polarization

Linear, vertical

6. Connector Type

u.FL / IPEX (direct to module)
SMA male (with pigtail adapter)
(specify which connector you need)

7. Form Factor

PCB antenna (compact, low-cost)
Wire whip
External whip (SMA)
Patch / Yagi (gateway, directional)

8. Radiation Pattern

Omnidirectional for nodes (donut shape)
Directional for base station / long-range link

this would go a LONG way in solving the mystery
