Waterproof 5.8dBi Lora 915MHz Fiberglass Antenna with 20Ft Low Loss KMR195 Cable for Helium Hotspot RAK Nebra Bobcat 300 SenseCAP M1 Hotspot HNT Miner Heltec V3 Meshtastic LORA32 915MHz LoRa Module

This is a really nice antenna. It should be noted that this is not an Omni directional antenna and that is noted inside the box by the manufacturer. It definitely does have directional gain and at least with the unit I received, the high gain lobe is in line with the label printed on the antenna by the Mfg (and likely 180 degrees opposite). It's well built, easy to assemble and install and is performing well. and I'm pretty sure will hold up over time. I would buy this again.

I purchased this fiberglass antenna advertised for 900 MHz use, and after testing it with a NanoVNA, I discovered it resonates closer to the 880–890 MHz range rather than right at 915 MHz. Build quality is solid, the fiberglass enclosure feels sturdy, and it mounts easily to a standard mast, making it a durable outdoor option. In real-world use with LoRa/Meshtastic gear, performance is acceptable, with an SWR around 1.4–1.5 at 915 MHz, which is workable but not as efficient as a properly tuned 915 MHz antenna. If your project or region uses the 868/880 MHz band, this antenna is a very good match. However, for US ISM 915 MHz applications, you’ll get better efficiency and range with an antenna specifically tuned for that frequency. Overall, it’s a decent product, but not the most accurate for 915 MHz users.

The build quality on this antenna is impressive. I’ve been searching through Amazon for a 915 MHz option, but most of the ones I found were either the wrong band or overpriced. This one hits the mark — I measured about a 1.5 SWR at 906 MHz, right where the LoRa radios operate. It feels sturdy enough for mobile use as well. I paired it with an N-to-IPEX adapter to connect it to my node, and it’s been working flawlessly. For the cost, this antenna is an excellent value.

I saw disappointing results with my portable node (probably because it shipped with a junk antenna) so I bought this roof kit mostly to see if Meshtastic even has a presence in my area. Height is might when it comes to radio so it's sometimes hard to tell if the problem is your gear or lack of activity. It does indeed work but I should add "in spite of the included coax". According to the experienced users I've talked to (funny how you never find them until after you've spent money lol), if you need 20 feet of coax between your Meshtastic node and antenna, it had better be the expensive, high quality stuff that's at least as thick as your thumb, which is why most of the outdoor nodes you see have the antenna mounted directly to the node's weatherproof enclosure. The fact that it works at all with this much thin coax is probably a testament to the high quality of the antenna. Wasn't impressed with the mounting hardware but it's good enough for an antenna of this size. If I ever get another day off with decent weather, I'll have to get out the ladder and see how well it works connected directly to the node.

This is a great antenna for meshtastic. Bulky mounting hardware, nice fir and finish. I have this mounted on the roof next to my TV antenna, and it has held up without any issues. I am picking up nodes a few miles away, wish I could get it higher to pickup more.

I seldom give a 5 star rating, but this antenna and mounting hardware are very well built! The U-bolts with the mounting bracket are heavy duty! And the signal from my Heltec V3 has increased 10x or better! I was only receiving 6 to 8 nodes on Meshtastic net. Now I'm receiving over 30 or more nodes all with good signals. The cable that came with the antenna is only 20 feet, so I mounted my antenna in the attic. FYI: There is no metal in my attic. This antenna really performs! I highly recommend this antenna and mount! You won't be disappointed!

This product is a fraud. I wish I can choose zero stars, but I cannot. It is sold as a 902-928MHz, 5.8 dBi antenna, and it is physically impossible that it is. It's not. Allow me to explain. By way of background, I have been a professional antenna designer and consultant in antennas for three decades. I live, breathe and eat antennas. A buddy of mine got into the Meshtastic Node radios, and dragged me along. He found a shopping list from a respected practitioner of the node art, and wanted to purchase a particular antenna... this one. I suggested that I buy one in parallel and use it for my node. For the price, it would be a time-saver. When it arrived, I initiated a video call with my friend and proceeded to test in my lab. I found a problem during the electrical evaluation, which involves monitoring the Return Loss while moving a finger up the length of the antenna. It was unresponsive at the top of antenna, which should have been the "hottest" part. Then, I used a strong flashlight to see through the radome (which I believe is PVC). I saw what appeared to be two bits of foam in the lower half... I could not resolve the conductor. But, in the upper half I saw nothing, which was consistent with my other observations. I told my friend that I believe that the upper half is empty, and that this was a junk antenna. He encouraged me to proceed to surgery, and see what was inside. He offered to cover the cost. I was right. The upper half of the antenna was air. The lower half did have a piece of wire, and I concluded that it was behaving like a half-wave dipole, NOT a two element colinear, which would have a gain close to the claimed 5.8 dBi. A simple dipole should be about 300mm long, and it would have a theoretical maximum gain of 2.2 dBi. A perfect two-element colinear would about double that, or add 3 dB for 5.2 dBi. I won't bother addressing the difference between 5.2 and 5.8..... not worth it. However, the missing structure in the top half of the radome was undeniable, and all the documentation misrepresented what this antenna was. Note that I did not address the impedance matching (Return Loss, SWR). The match was good! Meaning that the wire I saw in the bottom half of the radome was indeed trimmed to resonance. It was a collinear in dipole's clothing. We call that fraudulent. Do not buy. I returned mine.

Super happy with this antenna, made the difference between being acknowledged and not. I couldn’t get messages off before but now I have a ton more nodes detected and I can actually get message out. Paired it with a RAK 19001 and a 4631 core.

Internal core is identical to branded ALFA. Came stock with an SWR of 1.09 at 906.875. Not 5dBi, but if you want gain, get a longer antenna.

Llegó en tiempo y forma, físicamente tal como lo anuncian. Gracias muy buen producto y servicio.

I bought 2 of these antennas and set them Up in different locations for my helium minors. The just don’t work! Now I have to buy other antennas. Waste of money.

Extended my range on my Mestastic very far! picking up a ton more nodes
