Fiberglass LoRaWAN Antennas
Data Alliance Fiberglass Omnidirectional Antennas for LoRaWAN Networking
Weatherproof, durable omnidirectional antennas for long-range LoRa networking.
The four versions of omnidirectional fiberglass antenna that we carry for LoRa, include the following three gains:
- 3 dBi - a lower gain LoRa antenna suitable for dense environments like urban areas.
- 6 dBi LoRa antennas for "in-between" situations.
- 9dBi - a high-gain LoRa antenna that can be used to support extreme long-range connectivity in open terrain.
LoRa Antennas with Fiberglass Radome
These LoRa antennas have weatherproof and durable fiberglass radomes. Fiberglass is an excellent material for outdoor installation as it is lightweight, making secure long-term mounting easier. ~In addition these antennas are UV and corrosion-resistant, with excellent resistance to temperature extremes for added longevity.
LoraWAN networks are a versatile solution for providing connectivity for IoT devices and applications. This long-range, low-energy, and low-data form of networking can support a variety of nodes separated by long distance through the use of suitable antennas.
The Data Alliance selection of fiberglass LoRaWAN antennas (3dBi, 6dBi, and 9dBi) are designed to enhance the coverage that can be provided to devices that participate in a LoRa network. By using these antennas the signal quality and coverage for the LoRaWAN network can be optimised.
These fiberglass antennas are designed to be used as external antennas for LoRaWAN gateways. They can easily replace the existing small dipole antennas on LoRa gateways and they are connected to the gateway directly, or via an antenna cable. The antennas can be positioned wherever required to ensure line of sight.
Fiberglass omnidirectional antennas for the world's leading LoRa network
These LoRa antennas are suitable for use in both public, shared, enterprise and private networks. They have a high degree of interoperability with a wide variety of network providers that use the LoRaWAN® open protocol, to support IoT applications. These include:
- The Things Network
- AWS IoT Core for LoRaWAN
Fiberglass omnidirectional LoRa antenna features
Data Alliance's fiberglass LoRa antennas are designed to provide maximum LoRa coverage and connectivity. They make an ideal choice for LoRa network deployment at any scale. Key features include:
100% interoperable with LoRa hardware and networks
As these fiberglass omnidirectional antennas operate in the 915 MHz frequency band they will be fully compatible with the leading LoRaWAN gateway brands. They can be easily connected to indoor gateways via a length of antenna cable or outdoor LoRa gateways directly.
These antennas a suitable for use with LoRa gateways from leading manufacturers with models that include:
- The Things Indoor Gateway
- LORIX One Gateway
- Opensource LoRa Gateway
- Ursalink UG85 Indoor Gateway
- Robustel R3000 LG LoRaWAN Gateway
- Laird RG1xx Series
- Kerlink Wirnet iBTS
- Mikrotik wAP LR8 / LR9 kit
- Cisco LoRaWAN Gateway
- Linklabs LL-BST-8 Gateway
- Gemtek LoRa Indoor Pico Gateway
- AAEON AIOT-ILRA01Gateway
- Lorrier LR2 Gateway
Collinear LoRa antennas
The fiberglass radome of these antennas hides a powerful collinear design consisting of an array of multiple dipole antenna elements. These antennas multiply the standard dipole that comes with a LoRa gateway as each element becomes an extension of the adjacent elements in the array. This multiplies the overall directive gain of the antennas.
These LoRa antennas provide robust and reliable 360-degree coverage.
915 MHz ISM frequency band
These LoRa antennas are designed for use in ITU Region 2. They operate in the 915 MHz licence-free ISM frequency band.
Vertically polarized antennas for Helium
These LoRa antennas are vertically polarized. They transmit and receive radio waves that move perpendicularly to the surface of the earth. LoRa gateways and end nodes normally use either horizontal or vertical polarization.
RoHS LoRa antennas
All LoRa fiberglass antennas are manufactured in compliance with the Restriction of Hazardous Substances directive. We ensure that any metals used are from sources that are free from conflict and forced labor in compliance with the Conflict Minerals Directive.
Fibreglass LoRa antenna physical specifications
Here are the physical specifications of the Data Alliance fiberglass omnidirectional Helium antennas:
- Dimensions: length 114.5 cm (45 inches) width 3.4cm (1.34 inches) height 3.4cm (1.34 inches)
- Weight: 1.5kg (3.3 pounds)
- Radome: fiberglass
- Color: grey-white
- Connector: N-type
- Lightning protection: direct to ground
- Max wind speed: 180km/hr
- Max humidity: 100% at 25 degrees Celsius
- Temperature range: -40 to +80 degrees Celsius
Fiberglass LoRa antenna electrical specifications
Here are the electrical specifications of the Data Alliance fiberglass omnidirectional Helium antenna:
- Frequency range: 860 to 960 MHz
- Gain: 3, 6, or 9 decibels
- Characteristic impedance: 50 Ohms
- Power: 50 Watts
- Voltage Standing Wave Ratio (VSWR): less than 1.9
- Half Beam Power Width (HBPW): Horizontal - 360 degrees Vertical - 14 degrees
To achieve the best LoRa network coverage, a LoRa antenna should be located outdoors. The antenna should be mounted at height ideally with obstructions in the Fresnel zone kept to a minimum and line of sight maximized. The antenna used must match both the frequency and polarization of the LoRa gateway and end nodes. LoRa networks (antennas and end nodes are usually vertically polarized) so this antenna will need to be mounted in an upright position.
Mounting a fiberglass LoRa antenna
A u-bolt kit can be used to securely pole-mount a LoRa antenna vertically and at a height so that their gain and directivity in the horizontal plane are maximized. The u-bolt enables the antenna to be safely secured to a mast or pipe.
The Data Alliance u-bolt set with a chrome base can be used to mount collinear LoRa antennas on a variety of structures including window sills and rails. Here is how to mount a fiberglass LoRa antenna using u-bolts:
- Fiberglass Helium antenna assembly
- LMR 200 antenna cable
- Data Alliance U-bolt clamp kit containing:
- ○ 2 U-bolts
- ○ 2 Clamp plates
- ○ 4 Hex nuts
- ○ 4 washers
- ○ chrome base tube
A single u-bolt should be loosely assembled and placed over the top of the chrome base tube. The second bolt can be added and placed over the tube and both u-bolts tightened. The antenna can be fed into the base tube with the antenna cable connected at its base. The connector should be weatherproofed by using silicone grease and coax sealant tape.
