T-urbo-T 20 / LTE - directional DVB-T antenna
T-urbo-T logo

The T-urbo-T 20 antenna includes innovative T-urbo-T technology thanks to which the product is resistant to interference coming from LTE 800, GSM 1800, 3G systems.
Elements of the T-urbo-T-20 antenna were selected in such a way as to optimize the antenna gain within the range of 470-790 MHz. Above the frequency of 79 0MHz a sudden collapse of the characteristics of the antenna may occur which additionally eliminates the LTE signals.
The application of T-urbo-T directional antenna allows to reduce problems with reception of signals which in case of SFN transmission come from similar directions. In such a case it often turns out that the reception of DVB-T with the application of antenna with large half power beam width is not possible. Thanks to its strong directionality, the T-urbo-T antenna allows for:

  • reception from only one primary transmitter eliminating the illumination-increasing transmitter
  • or the other way around from the illumination-increasing transmitter eliminating the primary transmitter. Even better effects of elimination of the aforementioned phenomenon can be obtained by means of T-urbo-T30 antenna.

Special attention should be paid to the solid structure of the antenna and high-class materials used for its production:

  • carrier of the antenna (profile) has the section size of 20mmx20mm, with the wall thickness equal to 1,5mm;
  • directors and reflectors have the diameter 8mm, with the wall thickness equal to 1mm.

Thanks to the aforementioned materials’ parameters, the antenna is resistant to weather conditions and should last long years of use. This conclusion results from experiences in use of the previous Telkom-Telmor directional antennas which, in spite of very long time, are still operating.

Product features:

  • directional DVB-T antenna,
  • gain 9...14dBi,
  • T-urbo-T technology,
  • built-in LTE filter,
  • very robust mechanical construction,
  • dipole got the ABS casing,
  • weatherproof,
  • small half-power angle.
