915MHz Lora Antenna Long Range 15dBi 86inch with 32.8foot SMA RG58 Cable for Helium Bobcat HNT Hotspot Lora IoT Bobcat RAK Miner Longfi LoRaWAN Blockchain

I tried pre built, and tried building, a dozen plus antennas for 906.875mhz. This is the one I finally decided on. Good build quality. The coax it came with is trash and as tight as the bends were, it's probably ruined. I understand it has to put it in a box for shipping but looked like the packer had no idea what coax was. I wasn't planning on using it anyway but don't have any complaints about the antenna. Photo is with antenna mounted on a grounded mast after 10 feet of lmr-400. I highly recommend this antenna for meshtastic in the USA. -UPDATE I apologize for photo quality. 1.093 swr @ 906.9. It's been up there 2 months through a couple decent storms. Performance unchanged and now I can speak to the build quality. I'd give it 5.5 stars if I could.

I got this antenna and ran it through my VNA and was impressed at the numbers I got. Very low SWR in the 915MHz frequency (and especially 906.875MHz where you would want to use it for Meshtastic) which was my intended purpose for this antenna, but after checking the data sheet that is located on the SignalPlus web site, it reads 10.5dBi not 15dBi. I contacted both the Amazon seller as well as tech support at SignalPlus and they confirmed that this seller IS in fact their distributor on Amazon but with regards to the 10.5dBi vs 15dBi numbers "The antenna can be 15dbi, BUT only under very ideal circumstances and only at high frequency point." So that the frequencies most people would use it for (in the 900-920MHz range), plan on 10.5dBi of gain. If you want to use it above 1GHz, you might get 15dBi out of it.Having said that, this is a great antenna and I do recommend it. It has very good gain for Meshtastic ... at the full +22dBm power output of most transmit units, and a reasonable amount of low loss coax, you will be at or slightly above legal limits for transmit power for ISM devices. The build quality is excellent and comes well packed and arrived fast. The 32 feet of RG58 is of good build quality, but the included RG58 cable is the wrong cable for the 915MHz frequency. Even with a perfect 1:1 SWR, the coax will lose 5.087dB (69% of your power at .25w). By comparison, LMR-400 of the same length, only has a loss of 1.285dB or 26%.Again, this is a quality antenna, but you should count on lower antenna gain numbers and if you are operating at 900+ MHz, sell the included cable at a hamfest.

OK.

I got this for one of my areas main stay meshtastic relays, and it's giving clear signal to people 30 miles and more. So far the most effective node i have made, because even at those ranges the signal clarity is so good the acknowledgement on messages is very quick The cable is comes with is pure garbage and should not be used, and honestly would be better if they didn't include it. But since the antenna is what matters here, it's worth getting if you need a high dbi antenna

took the gamble, got the antenna, and threw on the nanoVNA, got a 1.13@900mhz and 1.24@920Mhz. I tossed it up on the roof with a heltec in a box. It works fantastic, getting nodes about 3-4 miles out.

Got better rewards with my 4 dBi that sat in my window then I did with this 8dBi I put on a pole on the roof. Very disappointing . Was getting 300 pretty consistently daily dropped to 180-220 daily.

This antenna flat out works great! I’ve tried a couple antennas for my Rak helium miner. The stock antenna, a 3db, a 9db, and this one doubles my earnings living in a saturated city with sub optimal transmit scale. You can tell the quality is excellent.For anyone looking to buy a Lora antenna for your miner with similar situation as mine you should definitely consider this antenna. I’d also recommend purchasing a separate LMR 400 cable with it as the RG 58 cable it comes with doesn’t allow the antenna to utilize its full power potential and place it outdoors and as high as possible. My furthest witness so far is 37km. Also pick up a Sandisk extreme 64gb A2 microSD card to process blocks faster.

The quality of the antenna seems decent enough however the cable that comes with it is not worth your time, if you order this antenna also order a LMR 400 cable with it, I have a bobcat miner 300 my area has a few hot spots around me but spread out. The stock antenna would not get any witnesses, with this antenna I got 2, so it is slightly better. But with the 1.4dbi -1.8 dbi loss this cable has it reduced the DBI to around 4-4.4 hopefully this helps!

It’s a shocking decent antenna. The SWR of my example was 1.24. it’s decent build quality.

Excelente

I got this antenna to upgrade my current 4.5dbi antenna and after using this 8dbi antenna for 2 weeks straight, it did more worse than my 4.5 dbi antenna did. I changed back to the 4.5dbi antenna and getting better results. I don't even think this is s real 8dbi antenna.

Llevo usandola un día y ha mejorado considerablemente mis ganancias en helium, ocupo un hostpot syncrobit y de momento todo excelente, la recomienda completamente.

Excelente producto, llego antes de la fecha indicada, muy buen servicio del vendedor, te escriben antes para asegurarse que es el producto que necesitas
