8dBi Indoor 868MHZ Magnet Base Long-Range Cellular LoRa Gateway Antenna Aerial With 3M/10FT Cable for Helium Hotspot RAK Nebra Bobcat EasyLinkIn Syncrob Hotspot HNT Miner Mining

Antenna works okay, haven't tried with the mount or cable only antenna direct to the miner.

At the time of review, the price is £26.Firstly, the antenna boasts an 8dBi gain, which is an impressive feature that can significantly enhance the range and signal strength of your device. It operates on a frequency of 868MHz, making it suitable for Helium Hotspot, RAK, Nebra Bobcat, EasyLinkIn Syncrob, and HNT Miner Mining.The antenna comes with a 3M/10FT cable, which provides enough length to install it in a convenient location without worrying about distance limitations. The magnetic base of the antenna also adds to its convenience, as it can be attached to any magnetic surface, making it easy to mount and adjust.

Good quality antenna, since I started using it instead of the stock antenna my rewards has been increased x3 and did put my miner on the top 5000 with more rewards in last 7 days. Highly recommended

works much better then stock antenna for Bobcat 300. If weather condition above 0 Celsius you can definitely place it outside

Had to return as I haven't seen any improvement

Aerial damaged my HNT miner as witnesses fell to 0, never came back even after swapping for old antenna… I am gutted as I was waiting for this miner 8 months. Use only certified equipment!

8dBi Indoor 868MHZ Magnet Base Long-Range Cellular LoRa Gateway Antenna Aerial With 3M/10FT ........Brand: supaerialI was interested in this antenna because it had the magnetic mount which would allow me to fix it to the roof of my car and do a bit of range testing. Unfortunately, this is not going to happen.The antenna is supplied in a plain brow cardboard box, it consists of the antenna, magnetic base with just under 3m of coax, and an RPSMA to SMA adapter. The antenna screws directly onto the base, this also has RPSMA connectors. The magnet is very poor strength, I attached it to my radiator, and it just slid down under the weight of its own coax, so there was no way this could go on the car whilst driving. The coax is unbranded so no idea what the quality is like, it is quite stiff too and feels very cheap. I carried out some tests for resonance and SWR and found the antenna to be resonant at around 838Mhz, some 30Mhz low in frequency although it is quite wideband. I tried it on different surfaces, both metallic and non-metallic to find the best which turned out to be just sat on the living room floor, hardly an ideal place to have it. I tried it on the roof of my car, my radiator, windowsill, table, etc and results were very similar with only a slight change in the tuning.In use, I compared it with my home made ¼ wave vertical antenna and found it to be lower in signal strength than my ¼ wave which was very surprising. I think possibly a combination of off frequency and cheap quality coax to be the main factors.Unfortunately, this antenna does not deliver, very poor magnet, cheap coax, and not quite on frequency.
