Antenă TV DVB-T2 DIPOL Y3 PASSIVE COMBO cu polarizare H/V

DIPOL DVB-T2 Y3 PASSIVE COMBO TV antenna A2120 is a directional antenna, adapted for reception of digital terrestrial television DVB-T2 in the VHF band (174-230 MHz) and UHF band (470-694 MHz). Universal design of the antenna makes it possible to freely change the polarisation of V/H reception for both VHF and UHF bands. The antenna is made of aluminium, the steel structural elements are galvanised, so they have increased resistance to weather conditions. Black ABS plastic elements ensure structural stability and high aesthetics. The reinforced carrier (main profile) of the antenna guarantees a high degree of mechanical resistance (e.g. against wind or birds). Due to its relatively high passive gain, the antenna is suitable for use in community and individual installations.The Y3 PASSIVE COMBO model is characterised by high energy gain and very good matching of receiving parameters, resulting in stable and clear reception even in more difficult terrain conditions. Thanks to the use of a precisely designed circuit, the antenna effectively eliminates interference and ensures optimum directionality.The antenna's compact designhas been optimised to take up as little space as possible while maintaining appropriate performance characteristics such as energy gain, frequency bandwidth and directivity.The H/V polarised DVB-T2 Y3 PASSIVE COMBO antenna (28 elements) is suitable for receiving DVB-T2 digital terrestrial television in the VHF and UHF bands.Key features:designed to receive DVB-T2 terrestrial television signalsin the VHF band (channels 5-12) in horizontal or vertical polarisationin the UHF band (channels 21-48) in horizontal or vertical polarisationpassive mode operationdirectional characteristicsmade of aluminium and ABSreinforced main profileHermetic box with F-type connectorTool-free installation in 2 minutesBuilt-in LTE 700 filterApplication in individual and collective installations.compact dimensionsThe DIPOL Y3 PASSIVE COMBO A2120 antenna combines robust construction, high performance and simple installation - an excellent choice for users looking for a durable and effective solution for DVB-T2 digital TV reception.Installation of the antenna is easy fast and no tools are required. Video installation instructions are available here.The above solution makes the DIPOL Y3 PASSIVE COMBO A2120 antenna extremely universal. By purchasing it, the installer or user is assured that it will perform in any scenario - from strong signals close to the transmitter, to weak signals at a distance or reflected signal reception in dense buildings. The graph opposite shows the antenna's gain characteristics as a function of frequency. The Y3 PASSIVE COMBO antenna is characterised by a high level of gain in the VHF and UHF bands. For the VHF band, the maximum gain is approximately 7.2 dBi, while for the UHF band it reaches a maximum value of 14.1 dBi. This means that the antenna is much more directional and effective for both bands, resulting in better signal amplification. Compact dimensions in addition to greater mounting capabilities, ensure that there are no problems associated with long-term operation (including less susceptibility to the influence of wind). Compact packaging makes the SMART series antennas easy to transport.RECEIVING PARAMETERS CONFIRMED BY FIELD TESTSAntenna DIPOL SMART HORIZON, before its implementation for sale, was subjected to many field tests, taking into account the analysis of performance in the range from 10 to 100 km from a 100 kW transmitter. The tests included measurements in locations with different building densities, as well as comparative tests with other DVB-T2 antennas available on the market. The tests showed that this antenna is at the forefront in terms of reception capabilities. Without major problems, reception was achieved at a distance of 94 km from the transmitter (100 kW, low range of the UHF band, terrain profile with no terrain obstacles along the route), with signal power values in passive mode of antenna operation averaging 50 dBμV for the three channels, while the MER value averaged 30 dB. These values should be considered sufficient for reception by a single receiver. In the case of a larger installation, it would be necessary to use the active mode, which would increase the signal power by 15-20 dB, while the MER value by 2-3 dB.DIPOL SMART series antennas are convenient to install and stable after installation thanks to, among other things, mounts based on two wide clamps and wing nuts. The distance between the arms of the clamps is 63 mm, so the antennas can be installed on towers, pipes and railings with a diameter of up to 60 mm. The mount is made of 2 mm thick sheet metal. Its design allows one of the ends to be released so that it is possible to mount the antenna on the tower anywhere on it (and not from the top), without having to completely unscrew the nuts. In addition, the mount allows for a 5-stage antenna tilt adjustment to optimize antenna positioning
