LMR®-400 SMA-Male to SMA-RP-Male

LMR-400 Coaxial Cable Assembly, Fitted with SMA Male and SMA RP Male connectors.

LMR-400 Helium Assemblies – The Coverage enhancement

Times Microwave LMR-400 Cable assemblies significantly boost the RF signal range and coverage for Helium Hotspot devices such as the HNT Nebra Outdoor/Indoor Hotspot Miner and the RAK Hotspot Miner.

This high-performance upgrade directly translates to higher revenue potential due to more efficient RF signal transmission from your Hotspot device to the Antenna.

Best of all, the low-cost nature of these assemblies ensure a speedy payback of your investment in these system performance-critical components. With recent regulatory changes to reduce the allowable output power of these devices, every dB of signal loss is more critical than ever – as it directly translates to reduced Hotspot performance and presents an additional new challenge when mining for Helium HNT currency.

LMR-400 Cable assemblies – Low Loss Helium Interconnect

Previously Hotspot devices in Europe had a higher Power Output rating. Now that there is a new restriction on output power in Europe, it has never been more important to use LMR-400 Cable assemblies as the perfect low loss interconnect.

Previously, “RG” type coaxial Cables were used between the Helium Devices and antennas.  RG cables are now a very undesired option due to their very high loss characteristics – combined with their ability to increase their Attenuation over time – directly resulting in degraded Hotspot range and coverage.

LMR-400 Cable Assemblies Vs RG-58 Cable Assemblies

• RG-58 cable RF Signal Insertion Loss over 10 Metres at EU 868 MHz  Frequency is nominally  5.2 dB (that’s only 56.4% efficiency)
• LMR-400 Loss over 10 Metres at EU 868 MHz Frequency: 1.4dB (Much higher coverage, 74.8% efficiency!)

The difference between the two is 3.8 dB’s – even 3 dB’s is a huge improvement of x 2 the Power Output, this is a very dramatic performance boost!

Our connectors are waterproof if connected the right way. We do highly suggest wrapping waterproof tape around the connections that are outside susceptible to rain to prevent any moisture from coming in and weakening the signal.
