Antenna devices

  • Long-standing tradition and expertise in designing and producing antennas and HF devices.
  • Primary focus on antennas designed for VHF/UHF frequency bands, covering the range of 27 to 1,000 MHz.
  • T-CZ has inherited and enhanced an original portfolio of antennas previously developed by TESLA Pardubice.
  • Tailored solutions, allowing adjustments for frequency bands, cable lengths, connector types, and mounting options.
  • Testing facility suitable for accurate antenna measurements and electromagnetic field analysis.

T-CZ is a company with a rich heritage and extensive experience in designing and manufacturing antennas and HF devices, with a particular focus on VHF/UHF frequency bands ranging from 27 to 1,000 MHz. Building upon the original portfolio of antennas initially created by TESLA Pardubice, T-CZ has continued to innovate and refine these offerings.

We offer customization services based on specific requests, including adjustments to frequency bands, cable length, connector types, and mounting solutions. Additionally, we can design bespoke antenna solutions, such as antenna sets, drawing upon our technical expertise and advanced machinery.

T-CZ runs a testing facility equipped with a free-space test range, minimizing reflections and industrial interference during antenna measurements. This facility is open to external customers, offering services for VHF/UHF antennas, electromagnetic field analysis, and radio interference measurements. Our antenna product portfolio is organized into several tiers, requiring customers to specify their desired product parameters. For certain antenna types, additional accessories like brackets and antenna cords can be ordered separately to tailor the solution to individual needs.

Detailed information

In a cord, suspension and miniature (miniflex) version for frequency bands of 40, 80,160, 300 and 450 MHz.

For radio stations, car radios, mobile radio telephones and civil radio stations (CB). They are manufactured for frequency bands of 27, 40, 80, 160, 300, 450 and 900 MHz.

Specifically designed antennas for railway vehicles or other applications requiring climatic and mechanical resistance. They are manufactured for frequency ranges of 150, 450, and 900 MHz, with the possibility to integrate an active GPS antenna in the 900 MHz band.

For radio communication applications (base, relay station, etc.). Manufactured base antennas are omnidirectional or with directional pattern and gain in frequency bands of 40, 80, 160, 300 and 450 MHz.

Special broad-band directional antennas covering the bands of 30 – 108 MHz and 100 – 500 MHz (aviation band I and II). These antennas have been designed for stationary use, and can be easily assembled and adapted for transport. Typical applications are in the field of tactical and aviation communication, or radio monitoring or radio jamming.

Broad-band vehicle antennas designed for the frequency band of 100 – 500 MHz with high power rating, intended especially for radio jamming devices.

Appropriate for ADS-B application, completely developed and manufactured by T-CZ, gain of 11 dBi, available in small and large versions.

  • Duplexers enable the operation of several base radio stations with a single antenna system. They can also be used in mass networks. Duplexer systems are manufactured for frequency bands of 160, 300, and 450 MHz.
  • Vehicle duplexers – for merging a radio station (140 – 500 MHz) and a car radio (0 – 108 MHz) to a common vehicle antenna.
  • Reflectometers
  • Cavity resonators
  • Hybrid circuits
  • Duplexers
  • Dividers
  • Filters
  • Power dummy loads
  • Construction elements for the creation of a duplexer system, or independent use, especially in base applications.
