Full Spec Sheet

This is compatible with the RAK V2, Bobcat 300, Nebra Indoor/Outdoor, SenseCAP M1, SyncroB.it, Helium Hotspot, Kerlink & LongAP. (915 MHz USA and Australia versions only).

This is a rigid solid antenna with no elbow bend point, therefore if you plan to use directly with your miner without using the magnet base, please note this. We recommend using with the included magnet base for maximum performance.

Is this 5.8 dBi indoor antenna comparable to the Rokland 8 dBi outdoor antenna?

This is shorter at 15 inches, not weather proof, and best to put in a window, or a more open area inside vs. where your miner sits. Our outdoor antenna is more effective for IoT equipment/miners if you do not have a high density of other hotspots around you. However, this indoor kit could be a good upgrade over just having your factory antenna connected to your miner if an outdoor antenna is not possible (some HOAs do not allow an outdoor antenna for example).

Beware cautious of gain inflation- some places arbitrarily inflate antenna gain number to appear better than competing products. Because gain cannot be easily measured by the end users, we have seen similar antennas marketed as numbers like 18 dbi to 30 dbi that are not even 20 inches tall. Why buy a 5.8 dBi when you can get a similar looking "18 dbi" for the same price, right? Rokland has been making antennas for over 14 years for WiFi, 4G, and other applications. Our 915 MHz antenna are listed with actual specifications. You also do not want extremely high gain as your path will be very narrow and miss other hotspots.

I see similar looking antennas online that say for 600 Mhz to 2700 Mhz, is a wider frequency spectrum better? 

Antennas with a focused spectrum will have better performance on that band segment vs antennas with very wide spectrum. We would not recommend using antennas that are also WiFi 2.4 Ghz compatible with your mining equipment. This antenna has a frequency range of just 900-930 Mhz to give you maximum performance.

More about this kit

You can use the included magnet base with the factory antenna of any of the listed miners, or with the included 5.8 dbi antenna. As gain increases, your vertical path will decrease, allowing you to communicate with hotspots from a greater distance but reducing your ability to be in the path of closer hotspots. As your community experiences new miners over time, it may be necessary to adjust what antenna you are using to deal with the density.

Frequency range: 900-930 MHz
Gain: 6 dBi
VSWR<2.5:1
Polarization:Vertical; Directivity:Omni-Directional; Material:ABS,Copper
Antenna connector: RP-SMA male; Impedance:50 ohm; Antenna height:39cm/15 inches

Low loss shielded cable

Our cable includes 11 feet of CFD-200 shielded coax cable built-in, with RP-SMA termination (to connect to your miner). CFD-200 has a gain loss of just 1.1 dB at 11 feet. Lower cost bases generally use RG58 cable which has a loss of 1.7 dB, over 50% more loss.

Recommended Use

Use with your Nebra, Bobcat, or RAK miner to help increase your coverage area. This is an indoor antenna and not rated for outdoor use. Check for Rokland brand outdoor mining antennas online. We recommend placing this inside near a window, or in a more optimal place for sending and receiving than where your miner currently is.

Great Indoor Antenna Kit, a must Buy to increase witnesses and HNT Rewards

I bought the 5.8 dBi Indoor Antenna Kit from Rokland for my Bobcat Miner 300. Installed it in the Attic and my HNT earning increased 3 folds in a week as i was able to get more witnesses. I'm super happy with this Antenna and recommend it if you are not getting those witnesses and HNT rewards

5.8 dBi indoor antenna is Excellent

I purchased this antenna because the stock 1.2 dBi antenna was not even communicating with other hotspots in my neighborhood (my house is brick and well insulated this may have been the problem). After receiving my new antenna from RokIand I mounted my hotspot as high as I could in my bedroom and ran the antenna wire into the attic. My antenna is indoors at about 7m high. My hotspot now communicates with all of the hotspots in my neighborhood and some up to 7.6km away. So for anybody out there wondering if putting this antenna in your attic will do you any good my experience is yes it will. (my roof is just plywood and one layer of shingles) Very good antenna for the price and I had it installed in less than an hour. I just screwed a metal plate to the rafters and stuck the antenna on that. (make sure to use a level) The increase in HNT paid for this antenna in the first week of using it. I think I’m going to try the 8 dBi Omni Outdoor 915 MHz Antenna outside in the future when I have more time to put it up but for now I am very satisfied with my purchase and making more HNT than ever.
