TETRA Antennas
- further categoriesEDR TETRA transceivers are used for critical communications. For example, ambulances, firefighters, police or utility companies, and even soldiers use this type of communication device. Today, it is one of the most popular voice and data communication technologies in this segment. But what do these acronyms mean? TETRA stands for Terrestrial Trunked Radio, which means digital trunked radio communication. As a global standard, TETRA is characterised by excellent sound quality and a high level of secure information exchange. Read more...

This standard has been developed by ETSI, the European Telecommunications Standards Institute, in collaboration with leading manufacturers, service providers and user organisations. And EDR stands for Endpoint Detection and Response, which covers endpoint protection and two-sided technology. This type of transceiver guarantees secure voice and data transmission, excellent functionality and a wide range of performance features.
What frequency ranges does the EDR TETRA antenna operate in?
Terrestrial Trunked Radio, or TETRA, transceivers and their antennas use time-division multiplexing, transmitting the radio frequency signal in the frequency range 380-430 MHz with a pulse frequency of 17.6 Hz at certain intervals. This pulsing can induce extremely low frequency (abbreviated ELF) modulation of the magnetic field.
What type of connector does the EDR TETRA antenna have and what devices is it compatible with?
There are antennas that can be attached to handheld radios, and some that can be attached to the windshield of a car. In this case, you will need to use a self-adhesive EasyFit EDR TETRA antenna, connected to the transceiver with an RG-174, 50 ohm coaxial cable and a BNC plug. This type of antenna is compatible with two-way transceivers.
How can we optimize the performance of the EDR TETRA antenna for the given environmental conditions?
When installing a windshield-mounted EDR TETRA antenna, it is always advisable to mount this type of self-adhesive antenna on the highest point of the car glass. This will always give the best performance for the device. If you are using a hand-held radio, you can choose either a 55 or 80 mm antenna, the larger version also having a higher power output.
What are the design features of the EDR TETRA antenna for maximum performance and noise cancellation?
Because the brand's designers placed great emphasis on harsh conditions and heavy use, they have designed the devices with these aspects in mind. The antenna is therefore coated in a high-strength but flexible plastic. But it's not just the antenna that has these positive characteristics, but also the device itself and all the accessories that can be connected to it.
What safety measures should be taken into account when using the EDR TETRA antenna?
These types of antennas that can be connected to handheld radios are 55-80 millimetres long, which means that they can get caught in another object during use, which can cause the transceiver to fall out of your hand. This can cause damage to the device. To avoid this, use a transceiver holster or belt clip, but you can also get a vest to which you can effectively attach your transceiver. In this case, the antenna will not hinder your movement and you will not have to worry about damaging the device while wearing it. However, when using the transceiver, make sure that you do not switch it on in a place where it could cause interference or danger.
Are additional accessories or devices required for optimal operation of the EDR TETRA antenna?
Of course there are. After all, in an emergency situation, every move makes a difference. Therefore, as mentioned above, use a transceiver harness and belt clip. But what other accessories should we use to ensure fast and decisive communication? Motorola offers a wide range of accessories, such as headphones, speakers, mobile microphones, earphones, headphones, headband microphones. These accessories greatly help you work quickly and professionally.
