4 dBi N-Male Helium Hotspot Fiberglass Outdoor Antenna & Bracket Mount for RAK, Bobcat, Nebra, SenseCAP

$13.00 $38.97

This is an outdoor fiberglass encased omni-directional 915 MHz N-Male antenna with 4 dBi gain. Also included is an outdoor bracket designed for mounting to a pole or PVC pipe. THIS DOES NOT INCLUDE THE RAK MINER ITSELF.

This antenna is compatible with the RAK V2, Bobcat 300, Nebra Indoor, SenseCAP M1, Kerlink, Linxdot,, Helium Hotspot, Kerlink, FreedomFi & LongAP, (915 MHz USA and Australia versions + Europe 868 MHz also) but requires an RP-SMA male to N-female coaxial cable to fit, and we carry compatible coaxial cables. This has the same gain as the Bobcat factory antenna and would be a better choice for RAK or Nebra owners.

We do recommend RokTape to seal all outdoor connection points.

Beware cautious of gain inflation- some places arbitrarily inflate antenna gain numbers 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. Rokland has been making antennas for over 14 years for WiFi, 4G, and other applications. Our 915 MHz antennas 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 a 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 698-960 MHz to give you maximum performance.

Need a low loss shielded cable?
This requires an RP-SMA male to N-female coaxial cable to fit your miner, and we carry compatible coaxial cables.

Recommended Use
Use with your Helium miner to help increase your coverage area. This antenna can be used outdoors and is weather and dust-proof.

Compatible with:

Bobcat 300
Nebra Indoor/Outdoor
SenseCAP M1
Helium Hotspot

4 dBi N-Male Helium Hotspot Fiberglass Outdoor Antenna & Bracket Mount for RAK, Bobcat, Nebra, SenseCAP

Recomended 100% Good service is not often seen.

Excellent service, I had ordered an antenna, cable and lightning insulator that were mistakenly incompatible and they called me to confirm and select the correct one. Today such a service is not often seen. Also everything arrived 3 days earlier than expected. I recommend them 100%.

Unparalleled customer service

I purchased the 4dbi antenna to maximize Helium earnings and didn't get the activity/rewards I was expecting with this new antenna. Customer service reached out about my original poor review and helped me through my situation. Earnings are back to where they were with the stock and even better.

Don't work

I bought the 4 dbi antenna and didn't work at all. Left it up for a week and received 0 witnesses. I installed the stock dbi antenna and immediately received witnesses.

Great product, Even better costumer service

placed an order for this antenna, and some cable, there support team emailed me and called me to let me know that the cable I ordered was not compatible with the antenna. They where able to change the cable to a compatible one. Saved me a headache, and money. Very thankful for them catching my mistake!
