Helium Hotspot 4 dBi Outdoor Fiberglass Antenna & Cable Choices for RAK Bobcat

Description

Beware of gain inflation- gain can be arbitrarily inflated. Because gain cannot be easily measured, we have seen an identical antenna advertised as 8 dbi. In fact, we emailed the seller and they clarified the gain was much less but they changed the number to get more sales. Read about it and see a screenshot in our Rokland blog. Our company Rokland Technologies is US based and 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.
This is an indoor fiberglass encased omni-directional antenna with 4 dBi gain.
All orders come with antenna, bracket, and U-bolt mount with washers and nuts
Pick-a-cable or select no cable if none needed
You can choose the 3 foot 195 grade cable with bulkhead OR
A 16 foot LMR-400 equivalent cable with the correct connectors for the antenna and your miner. For 16 foot length, you want to have 400 grade shielding or better. This could be LMR-400, RFC-400, CFD-400, or Wilson 400. If you go with a higher loss cable like RG58 or RG174, you will experience degraded performance due to high cable gain loss.
Compatible Miners
This kit is compatible with RAK, RAK 2, Nebra Indoor, SyncroB.it, SenseCAP M1, or Bobcat miner (915 MHz USA and 868 Europe versions only).
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.
