2J EDR TETRA vehicle antenna - technical characteristics and application criteria
The documented frequency range of the TETRA/UHF antennas is 380-470 MHz. The reviewed configurations include 50 ohm impedance and linear polarization, while some versions specify an omni-directional radiation pattern. Specific electrical parameters such as VSWR, efficiency, peak gain, and maximum input power may vary by configuration, so these values should always be compared with the requirements of the radio system based on the technical data of the selected antenna.
What frequency range is used by a TETRA antenna?
The documented range of antennas intended for TETRA radio systems is 380-470 MHz, appearing in TETRA/UHF/LMR configurations. Within the category, both narrowband antennas with tunable centre frequencies and wider-band versions specified for the complete 380-470 MHz range are available. For this reason, antenna selection should not be based on the TETRA designation alone; the exact operating frequency must also be checked.
TETRA radio system and vehicle communication
The documented application areas of TETRA antennas include mission critical communication, government and public safety, first responder fleets, and fire departments. The category therefore includes antenna configurations suitable for vehicle communication systems where TETRA forms part of the onboard radio communication infrastructure. Actual compatibility must always be determined according to the frequency, impedance, power, and connection requirements of the radio equipment.
Which antenna mounting methods are available for vehicle applications?
The 2J TETRA range includes several mechanical configurations. Documented options include screw mount, connector mount, adhesive mount, wall mount, and magnetic mount solutions. When selecting the mounting method, the installation location, available mounting surface, and whether the antenna is ground plane dependent or ground plane independent should all be considered.
Vehicle antenna with screw, magnetic, and adhesive mounting
- Screw mount configurations use a mechanically fixed installation.
- Magnetic mount versions use magnetic attachment.
- Adhesive mount antennas are installed using an adhesive mounting method.
- Connector mount versions use the connector itself as part of the mounting arrangement.
- Some antennas are ground plane dependent, while others are ground plane independent.
The ground plane requirement is an important technical parameter. For ground plane dependent antennas, the documented performance values may be linked to a specified installation environment, while ground plane independent versions are designed without this type of ground plane requirement.
What does anti-rotation mounting mean for antenna installation?
Anti-rotation mounting appears among the documented features of some screw mount TETRA antennas. This forms part of the mechanical mounting design and should therefore only be considered where the selected antenna configuration explicitly includes it. Some outdoor versions also specify IP67, IP69, IP69K, or IK09 ratings, but these ratings cannot be applied generally to every antenna in the category.
Combined TETRA, GNSS, and mobile radio communication antennas
A TETRA antenna may be available either as a standalone radio antenna or as a combined configuration integrating several radio functions. Documented combinations include TETRA/UHF with GPS/GLONASS/QZSS/Galileo, as well as cellular, TETRA/UHF, and GNSS functions within a common antenna housing. These versions use separate connections for the individual radio functions.
Which functions can be combined in a TETRA antenna?
Combined configurations may include GNSS functionality in addition to the 380-470 MHz TETRA/UHF connection. The documented GNSS solutions include GPS, GLONASS, QZSS, and Galileo support with specified L1 frequencies. Some configurations also include cellular connectivity. The electrical parameters and connections of the individual radio functions remain separate from one another.
What should be checked when selecting a TETRA antenna?
We recommend selecting the antenna based on its complete technical configuration. Even within the same TETRA frequency range, gain, VSWR, maximum input power, mechanical design, ground plane requirement, and connection method may differ. Cable and connector options can also be configurable in some versions, so the connection requirements of the radio equipment should be checked as well.
2J antenna selection checklist
- 380-470 MHz frequency range and the operating frequency of the radio
- 50 ohm impedance where documented
- Linear polarization
- VSWR and peak gain values
- Maximum input power
- Ground plane dependent or ground plane independent design
- Screw mount, magnetic mount, adhesive mount, or connector mount installation
- Cable and RF connector type
- Number and function of individual radio connections in combined antennas
- Environmental rating where an IP or IK classification is specified
The technical parameters of the antennas within the category are not identical, so a single gain, VSWR, power, or environmental protection rating cannot be applied to all configurations.
