Ultra Low Loss Assembly for Helium Hotspot Mining
Our own brand of HNT-400 Ultra Low Loss coaxial cable is designed to deliver high performance with minimal loss. It is equivalent to LMR-400 and greatly extends the range and coverage of Helium Hotspot devices.
This high-performing upgrade directly translates to greater revenue potential because the RF signal is transferred more efficiently between the Hotspot device and antenna.
Hotspot devices in Europe previously had a higher power output rating. Now that there is a new restriction on output power in Europe (PoCv11), using HNT-400 Cable assemblies as the perfect low loss interconnect has never been more important to minimize signal loss.
Coaxial cables of the "RG" type were previously used between Helium Hotspots and antennas. The very high signal loss characteristics of RG cables - combined with their tendency to increase their signal loss over time - have rendered them a very undesirable option, leading to poor range and coverage of Hotspots.
HNT400 Vs RG58 - Performance Difference
- For EU 868 MHz the RG-58 cable RF signal insertion loss over 10 metres is 5.2 dB (that's only 56.4% efficiency).
- For EU 868 MHz the HNT-400 cable RF signal insertion loss over 10 metres is only 1.4 dB (Much higher coverage, 74.8% efficiency!).
The difference between the two is 3.8 dB’s – Please note that every 3 dB is a huge improvement of double the power output - this is a very impressive performance boost!
Note
This cable is N-Female, so you will need an antenna with an N-Male connector (like our 3 dBi, 4 dBi, 5.8 dBi or 8 dBi antennas) to connect the two.
