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.

Use this with Meshtastic Heltec v3. Works great. Improved performance.

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.

There is no greater bang for your buck to upgrade a LoRa Meshtastic Device.*** NOTE PLEASE SHUT OFF YOUR DEVICE BEFORE INSTALLING ****** DEVICE POWERED ON WITH OUT ANTENNA WILL COOK YOUR DEVICE ***The stock antenna on my LilyGo T-Echo was 7.87:1 SWR and 24.84 ohms resistance. I was barely able to pick up nodes on the device - even in optimal high ground locations.When I upgraded to the Tenmory 3dbi antenna I gained SIGNIFICANT IMPROVEMENTS! The Tenmory 3dbi in a Straight - Vertical configuration is a 1.28:1 SWR and 40 ohms. Very close to an almost perfect antenna and fairly wide bandwidth across 900MHz to 930MHz. See pics.When I tested it in the 90° bent Vertical position it saw a degradation of performance. 2.9:1 SWR and 125 ohms. Still better than stock but I wouldn’t run it that way. Keep it straight.You can see the joint where it bends in the photo. I keep it in that position as a stress / strain relief when I put the device in a pocket. That way the joint bends before the unit breaks.Very well made. Great engineering. Easy to install if you power your device off. Fantastic results. Hitting some devices at 50+ miles direct.

Used for Lilygo tbeam. Nano vna tests show that the center frequency is indeed tuned spot on for 915Mhz. The swr on this antenna is 1.3:1 when straight out. When folding this antenna at 90 degrees, the swr goes to 3:1 which is a bit high. So for the best performance, leave it straight out! The 915 antenna that I got with the tbeam resonates around 680mhz and at 915mhz, the swr was 4.7:1 folded and 5.1:1 straight out - really bad. So these antennas are a VERY significant improvement compared to the lilygo 915 stock antennas.

These are the best alternative to the basic stubby antenna that comes with most LORA devices. Decent SWR readings negative SNR bd and RSSI dBm but about 50% better than the stubby.

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.

Tossed one of these on my LilyGo T-Deck and got a much better signal. Price is nice, it works for me. Now I want to mess with my RAK board's flat antenna and replace it with one of these too. Noticed a huge signal boost on the graphs in Meshtastic too for that device.
