Antennas by Application

Antennas for Smart Agriculture and Precision Farming

Connected agriculture spreads sensors, livestock trackers and autonomous machinery across wide rural areas, demanding long-range, low-power links and robust GNSS positioning rather than dense high-capacity coverage.

Overview

Understanding antennas for smart agriculture starts with the physics of the band, then moves through pattern, gain, mounting and the practical constraints of a live deployment. Sub-GHz LoRa and NB-IoT links cover farm-scale distances with a single elevated gateway antenna, while RTK GNSS guidance for tractors and sprayers needs centimeter-level positioning from a multi-band antenna.

Frequency Bands and Spectrum

The bands most relevant to antennas for smart agriculture are listed below. Each band brings different propagation, regulatory and antenna-size implications.

BandRange (MHz)Typical use
902-928 MHz ISM902-928US ISM / LoRa / RFID
800-960 MHz Cellular806-960GSM-900 / cellular
GNSS / GPS1176-1606GPS L1/L2/L5, GLONASS, Galileo, BeiDou
Wideband (700-2700 MHz)700-2700Multiband / all-cellular

Recommended Antenna Types

The following antenna classes are best matched to antennas for smart agriculture:

Omnidirectional Fiberglass Antenna

Collinear omnidirectional antennas in a UV-stable fiberglass radome for 360 degree outdoor coverage.

GNSS / GPS Antenna

Active GNSS antennas for positioning, timing and high-precision survey applications.

Magnetic-Base Mobile Antenna

Magnetic-mount vehicular antennas for telematics and mobile connectivity.

Directional Panel Antenna

Sector / panel antennas delivering focused gain over a defined azimuth, used for base-station sectorization and fixed point-to-multipoint links.

Applications and Use Cases

Antennas for Smart Agriculture support a range of deployments. The most common are:

  • IoT / M2M
  • GNSS Positioning
  • Asset Tracking
  • Telematics / V2X

Mounting and Installation

Gateway and base antennas are mounted on grain-silo, barn rooftops or dedicated masts for maximum line of sight; machinery antennas are magnetic- or bracket-mounted on cab roofs.

Lightning Protection and Grounding

Tall, isolated rural masts are lightning-prone, so surge protection and a low-impedance earth ground are essential for gateway and base-station antennas.

Standards and Compliance

Designs and deployments in this area commonly reference:

  • LoRaWAN
  • NB-IoT / LTE-M (3GPP)
  • GPS/GNSS RTK for guidance

Selection and Comparison

When narrowing down a model for antennas for smart agriculture, weigh these trade-offs:

  • LoRa vs. NB-IoT backhaul
  • Single gateway vs. mesh
  • Fixed vs. mobile GNSS

Typical gain for this category is 3-12 dBi, usually terminated in a N-Female / SMA connector, though the interface can be customized.

Frequently Asked Questions

What frequency bands do antennas for smart agriculture use?

Antennas for Smart Agriculture typically operate across 902-928 MHz ISM, 800-960 MHz Cellular, GNSS / GPS, and Wideband (700-2700 MHz). The primary band spans 902-928 MHz.

How should antennas for smart agriculture be mounted?

Gateway and base antennas are mounted on grain-silo, barn rooftops or dedicated masts for maximum line of sight; machinery antennas are magnetic- or bracket-mounted on cab roofs.

What antenna gain is typical for antennas for smart agriculture?

A typical gain range is 3-12 dBi. Higher gain narrows the beamwidth and extends range, so the right value depends on whether you need broad coverage or a focused long-distance link.

Which applications are antennas for smart agriculture best suited for?

Common applications include IoT / M2M, GNSS Positioning, and Asset Tracking. Sub-GHz LoRa and NB-IoT links cover farm-scale distances with a single elevated gateway antenna, while RTK GNSS guidance for tractors and sprayers needs centimeter-level positioning from a multi-band antenna.

What connector do antennas for smart agriculture normally use, and can it be changed?

The usual interface is N-Female / SMA. The connector and cable assembly can be customized — SMA, N-type, TNC, BNC, FAKRA and IPEX options are available on request.

Do antennas for smart agriculture need lightning protection?

Tall, isolated rural masts are lightning-prone, so surge protection and a low-impedance earth ground are essential for gateway and base-station antennas.

Which standards apply to antennas for smart agriculture?

Relevant standards and references include LoRaWAN, NB-IoT / LTE-M (3GPP), and GPS/GNSS RTK for guidance.
