Pickup available at 2251 NW 41st Street

Usually ready in 1 hour

New for 2022, Rokland introduces our large profile tuned 8.5 dBi 915 MHz 40" fiberglass antenna with N-male connector and U-bolt bracket mount. This is certified and designed for outdoor environments and is weatherproof. See photos for mounting instructions.

Important note: this is different from our low profile 8 dBi antenna, and this 8.5 dBi antenna has an
N-MALE antenna connector, meaning your cable must be N-FEMALE. Therefore if you have our low profile version and switch to this, you will need a different cable or a barrel converter.

This antenna is compatible with the RAK V2, Bobcat 300, Nebra Indoor, SenseCAP M1, Kerlink, Linxdot,, Helium Hotspot, Kerlink, FreedomFi & LongAP, but requires an RP-SMA male to N-female coaxial cable to fit, and we carry compatible coaxial cables. This antenna also works with other Helium hotspots (such as the Nebra Outdoor) but may need different cable connectors, please contact our sales staff if needed.

What is HaLow™?
Wi-Fi HaLow™ is "the designation for products incorporating IEEE 802.11ah technology, augments Wi-Fi by operating in 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."

Compatible with:

Bobcat 300
Nebra Indoor/Outdoor
SenseCAP M1
Helium Hotspot

Not great

I get better reception out of the small antenna on my portable device than I do this antenna at 32 ft above the house. It is hooked to an in connector mounted to the Box on the mast there is no coax so it is not due to loss.

Going from a small portable antenna to a large high gain antenna 32 feet in the air will drastically change your beam and make it much more narrow. This results in long distance point to point reception but may reduce reception to nodes or devices outside the narrow beam. Our support staff has reached out to you to get a better understanding of your use case so we can provide additional comment and assistance.

Excellent antenna. Working perfectly on my solar meshtastic node. Excellent coverage.

Excellent antenna. Working perfectly on my solar meshtastic node. Excellent coverage.

Big antenna works for meshtastic!

Using the antenna in meshtastic, manage to pickup another node 13 miles away! I'd say the antenna is working as intended.

If using a heltec decive with the UFL connecter like i am and want to pair with this antenna, be sure to grab Rokland's
"UFL(IPEX/IPX) Mini PCI to N-Female Bulkhead Pigtail Cable Extension"
