915MHz LoRa Antenna Indoor 3dBi Gain Omni SMA Male + U.FL MHF1 Cable 2 Pcs | 915 MHz LoRaWAN antennas with UFL MHF1 extension cable. Ideal for LoRa gateway & ESP32 OLED & 900MHz IoT devices

The first order had excellent SWR. My second order had one with an excellent SWR and the other one was Perfection. My small portable pocket Rak node has much better range now. Now I have two spare antennas, that means I have to order a couple of more heltech V4 nodes. The SWR measurements were done at 910.5 MHz near the USA/Canada Meshcore frequency. Edit: 4/11/2026 After on the air testing with MeshCore repeaters, and comparing other antennas, I ordered another (2pack), for use with my portable nodes. Currently testing one outdoors 20 feet up on a tower. It's waterproofed and working fine after snow and rain storms. I will take it down soon and re-install it after installing and testing it, inside a section of PEX pipe, to insure it's 100% water proof. These are great LoRa antennas!

I purchased this for a project for a school play prop using 2 RP2040 micro-controllers (Adafruit Feather RP2040 LoRa RFM95) , 1 for the prop and 1 for a remote. The receiving prop is a clock so originally I incorporated the antenna on the back, but I found that I could still easily send signals from the stage to the tech booth of the theater with only the connector cable attached to the clock (not the actual antenna) but with the full cable+antenna connected to the remote control. The distance is maybe 200ft so I'm extremely satisfied with the results. The build quality on these antenna seem excellent. Would purchase again if needed.

Seems like a quality antenna, the nano vna suggests they prefer being straight and not bended.

I’ve been using these 915MHz LoRa antennas for Meshtastic, and they’ve proven to be well-tuned for the 915MHz frequency used in the US. The signal-to-noise ratio (SNR) readings I get with these antennas are nearly identical to those from a known 2.5dBi antenna, so while they are advertised as 3dBi, I suspect the gain is closer to 2.5dBi. The hardware included is of decent quality, and the antennas perform best when used straight rather than bent at a 90-degree angle. For example, I have a PORTDUINO node set to CLIENT_MUTE on my desk in my basement office, and it consistently connects with nodes up to 3 miles away. These antennas are reliable, well-built, and a good choice for anyone working with Meshtastic in the 915MHz range. Despite the questionable gain rating, their performance and build quality make them a worthwhile purchase for DIY LoRa projects.

I'm in a meshcore dead zone, so I built my own repeater. Now, this antenna isn't magic, but I measured both antennas on the nanoVNA and pleasantly surprised: when straight, under 1.25:1 on most of the LoRa band, best at around 908 mhz. Bend it, however, and it goes up near 2:1. Still acceptable, but keep that in mind. I oriented my case to keep it straight.

These are good Mesh antennas with a low SWR as long as you have them straight and not at an angle. When you bend them, the SWR goes wonky.

It is no secret that the stubby antennas included with Heltec V3's are not particularly effective for getting good range. I was looking for an antenna upgrade for my two units and decided to give this pair a shot based on other positive reviews. I can confirm that these work great and for the price are a good bang for your buck to upgrade the performance of V3's. With the stock stubby antennas, I could receive messages inside my house but attempting to send messages out to the mesh would always fail. I have not had any message failures since swapping over to these antennas.

Great for Meshtastic builders. Comes with a long cable and great signal and the 915 MHz range. Good quality and good signal strength.
