The 6dBi Optimised Helium Antenna offers +7% forward Power Transmission compared to alternative non optimised VSWR Antenna designs.
- Results in higher coverage and Increased HNT $ revenue.
Interline introduce the 6dBi High Performance Antennas for use with the Helium Network offering superior Power Transmission compared to other commercially available alternative non optimised VSWR Antenna designs.
This new Antenna design has been specifically tuned to operate with peak performance over only the frequency band of interest to EU Helium Hotspot operators – the EU 868 frequency band.
These optimised Antennas feature a superior VSWR performances of 1.5:1 maximum – which immediately results in over +7% more transmitted, non-reflected Power from your Antenna and reduced Mis-match loss when compared to many of the commercially available 2:1 VSWR performance.
Most commercially available Helium Hotspot Antenna designs available today are designed to be universal – meaning that the one product has been designed to cover both the European EU868 and US915 Frequency bands – resulting in designs which may be non-optimised for either frequency range.
For certain applications, such as urban environments or when large areas of terrain need to be monitored, the Horizon 6dBi Helium City outdoor antenna will be the perfect addition to your Helium system.
It is a solid solution that provides extra power and coverage for Helium outdoor base stations.
The antenna has an average gain of 6dBi, length 54cm, frequency range 868-880MHz and comes complete with hardware for pole and wall mounting.
These antennas also receive strong signals from GSM 900MHz transmitters, operating in Europe with high powers.
This adversely affects the range and sensitivity of Helium-LoraWan devices, intermodulations may appear, especially near GSM antenna masts.
Our antenna has a built-in bandpass filter that works without attenuation in the working band of the antenna and is characterized by attenuation for other frequencies.
The filter, located in the antenna radiator, is a 1/4 wavelength segment shorted to the ground at 868 MHz, and a resonant slit in the socket module. Frequencies different from the antenna operating frequency are discharged to the ground. The filter attenuates unwanted signals by a few dB.
It is a specialized narrowband antenna operating in a dedicated band (EU868), which allows to obtain a high signal-to-noise ratio (SNR) and maintain high sensitivity of the receiver in the device.
The range obtained on this antenna is even several kilometers. The range depends on the mounting height, the type of Access Point, the quality of the antenna connector used (unit attenuation, length, quality of connectors), as well as the terrain and configuration of access points on the other side of the link.
In the construction of the heat sink, we do not use LC matching circuits (capacitance-inductance correlation) that allow for “artificial” antenna impedance adjustment and lowering the VSWR coefficient.
This causes an increase in induction or capacitance, which results in “blurring” of digital signals and has a negative effect on the bit / Hz encoding and the error rate (BER).
Our antenna works “clean, resistive” and has a very low self-noise figure and an excellent bit / Hz encoding ratio.
The antenna housing is grounded, which protects it against electrostatic discharge
(electric charges appearing on the antenna are discharged to ground)
For proper operation, the mast and antenna must be grounded to the existing lightning protection system.
Despite the lack of lightning protection of the device, the antenna mast and the antenna must be grounded.
The ground wire should be taken as short as possible and directly connected to the ground.
The mast mounted antenna should be grounded
to the antenna mast or to the cable with an equipotential bonding conductor
with a cross-section of not less than 8 mm2 Cu.
For additional safety, install a gas lightning arrester.
