Before returning your antenna, you may want to remember these key things. 1. Time- it can take a few days, in rare cases up to a week for a miner to synch with a new antenna. If it has only been online for a day or two, and you are seeing some beacon activity in the Helium app but no witnesses and/or low rewards or worse results than your factory antenna, more time may be needed.2. Double-check connections- if you have no activity at all on the miner and 0 earnings and more than 24 hours have passed, double-check to make sure your antenna cable is fully connected to the miner, and the antenna is fully connected to the cable. Make sure the antenna is upright and not laying down or at an angle.3. Elevation/change location- If you have some activity but lower than desired, elevation could help. If you are testing the antenna indoors at ground level, moving it outside and higher up can help. If you are still not seeing results, please contact our staff and we can further assist you with the return.
