8.5 dBi N-Male Omni Outdoor Helium 915 MHz Antenna (Large Profile 40") for RAK Miner 2 Nebra SenseCap M1 & Bobcat Hotspots

$26.00 $79.97

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

Wonderful results in Tampa Bay FL

I purchased this antenna and have it mounted on a mast at a height of about 11.5 meters and connected to a 25ft 400 LMA flex cable here in tampa bay. In my first 48 hours I have 42 witnesses! There are 3 other miners in my hex and I am the top earner now. Oh I also have a lightning arrestor installed at the base of the antenna. Love Rokland products!

Perfect. Now we in the money
