Bingfu 868 MHz LoRa Antenna Aerial Outdoor 3dBi Fiberglass LoRaWAN Antenna N-Male for Helium Hotspot Miner RAK HNT Bobcat + 1m N-Female to RPSMA-Male Extension Cable

Previously had a rak miner running with a standard antennae pointing outside my bedroom window - running at around 0.20 HNT a day. Bought this antennae on a whim to give it a shot for £30 - Ran the cable outside the window and screwed it to the UPVC (a 1m cable limited me doing anywhere else) and within 12 hours the miner is back up and running at around 0.40 HNT a day - looks to have doubled my efficiency.

Everything is perfect, quick delivery and good packaging.

The antenna and mounting kit are good. Be careful of the cable as it's only RG58A. If you're only using 1 meter it will be OK, but at 3 meters you will suffer a 1.6dB loss, add that to the 0.2dB for the connectors and you end up with 1.8dB loss.

perfect, it was the right choice for me

This is a 3dbi but a 5dbi showed up and my earnings decreased by 50%. Dissapointed

Despite being 10m i was hardly getting any witnesses on helium, swapped with a tuned version for similar price and income has now doubled. No idea what dbi this really is and its very short.

Not 8 dbi no difference from my old 3dbi.

Got used item, scratches everywhere scuffs on the antenna. Very disappointed
