2023 – Israel Projects. We successfully carried out 3 larger projects for an Israeli customer. These included technology delivery for indoor and underground areas coverage with a radio signal in 160MHz and 700MHz frequency bands. Due to the greater number of transmitted services and their mutual frequency proximity, the development of associated circuits that would ensure sufficient mutual isolation of individual systems was a big challenge. Two of the mentioned projects will continue in the following years when additional technology should be delivered to expand the current coverage area.

Solutions - SPORA


The Spora is a system developed for hidden communication between special police units. It provides hidden and safe communication between members. For information transmitting we use digital modulation which is secured with the help of the modern coded algorithm with the user defined key. The basic components of the system are personal radios, vehicle radios, vehicle repeater, portable repeater with remote controls and repeaters designed for special usage. All radio units go together with a large scale of accessories which provides high variability when using the system. A user has clear programming software for the system setting and the function of the radio. The design of separate elements of the system and accessories can be adopted to individual requirements of a user.

The radio goes together with special accessories which help to adopt it to the needs of each user. It is possible to use several types of antennas which can be integrated into an under arm case. For controlling of the basic operation regimes the radio is equipped with several types of special manual controls. They have an ergonomic shape and ensure a comfortable operation of the radio. The radio can be connected to a special hidden reproducer or different variants of head-phones and microphones. It is also possible to use Bluetooth hands-free. The delivery of accessories can be modified according to customer demands.




The tester of the system Spora enables a user to check the function of all radios and accessories of the system Spora and identify possible errors. It is used for measuring of radio parameters, audio-signals and digital signals. The tester substitutes many expensive measurement devices, e.g. VF generator, wattmeter, radio tester, audio generator and analyzer, voltmeter, ammeter and others. All tests are carried out from PC with the help of user-friendly software which is the part of delivery. The results of the tests are processed to a clear record.
