What is HaLow™?

Wi-Fi HaLow™ is "the designation for products incorporating IEEE 802.11ah technology, augments Wi-Fi by operating in the spectrum below one gigahertz (GHz) to offer longer range and lower power connectivity. Wi-Fi HaLow meets the unique requirements for the Internet of Things (IoT) to enable a variety of use cases in industrial, agricultural, smart building, and smart city environments.

Wi-Fi HaLow enables the low power connectivity necessary for applications including sensor networks and wearables. Its range is longer than many other IoT technology options and it provides a more robust connection in challenging environments where the ability to penetrate walls or other barriers is an important consideration."

Michael Kadlec
Excellent LoRa antenna

Needed some durable outdoor 915MHz antennas that were also somewhat low profile for permanent LoRa repeaters. With line of sight path, able to bounce LoRa signals over 100km through smokey atmosphere and storm clouds. The SWR was 1.21 @ 915MHz on the one I tested out of the five I received.

Default FedEx Shipping was incredibly quick to Canada, although be prepared to pay duty/import/tax fees to the courier on top of your shipped price.

Definitely better than the RAK stock

I needed this 5.0dbi as a quick cheap simple indoor antenna that my 81 year old father could setup for me. I dont have the perfect instal being its on the first floor of the house, but i have been getting 3x witnesses i recieved on stock antenna. I have been loving rokland and their business model. Quality products, shipping, and customer service. 👌

New Favorite Antenna

Solid profit
Perfect coverage for dense areas.
The Magnetic bases are excellent. I'd like a holder so I can put one on the end of a riser.

Juan Pradopio
Cool idea but no thanks

So I replaced my 4dbi 10 inch antenna that I got off Amazon for this one since it wasn’t too much smaller but it was a 5.8dbi. My rewards have gone down substantially, I didn’t change anything else. I am using it on the same miner, same location, and same height but the amount of witness and beacons have gone down. The mine is at a buddies house and I don’t want to bug him so I’ll leave it on for a couple more weeks but I’m planning on changing back to my Amazon one, unfortunately for me I bought 3 of these and won’t be using them again.

HI Juan, thank you for your review and we are sorry to hear your rewards dropped. Higher gain can help extend range but is not always better in all environments. A lower gain has a higher vertical beamwidth, so in your area, the lower gain may be accessing more witnesses. There have also been a lot of Helium network issues in the last couple of weeks, so earnings have been very up and down for many people, even with no antenna changes. Depending on what day you installed and how long it was left up, this could be impacting. Our support team has reached out to you directly to see if they can help troubleshoot or assist with a return.
