DVB-T2 Anténa Y3 PASIVNÍ KOMBINOVANÁ TV anténa s H/V polarizací

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.

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. The graduation increases the stability of the antenna during long-term use - the position once set will be retained, which can be a problem with antennas that offer infinite adjustment in this area (antenna drooping due to wind, birs, etc.).

It takes less than 1.5 minutes to install the antenna and no tools are required. Thoughtful design makes it easy to install. The antenna reflector, director holder and antenna box with loop dipole are mounted with a quick but secure snap. There are 2 wing nuts included with the clamp. No wrench is needed to tighten them.

The materials used for production will ensure long and trouble-free antenna operation in various weather conditions. Parts of the antenna are made of aluminum, steel structural elements are galvanized, and black plastic elements are made of high quality ABS. The reinforced main bar provides increased resistance to wind and birds. The ABS used has been modified to operate at -30...+80°C. To test the strength of the ABS reflector holder, the end of the top holder was loaded with 25kg. The antenna was not permanently deformed, the mount did not crack or break. The antenna could still be operated.

High gain of the antenna in passive mode and the possibility of switching on the signal amplifier built in the antenna box cause that the antenna can receive the signal even 40 km from the transmitter. This has been proven in field tests. Note, however, that this depends on a number of factors such as the strength of the transmitted signal, local terrain conditions, local interference etc.

The antenna is designed to receive signals broadcast in the UHF band on channels 21-48 (frequency 470-694 MHz). It is prepared for the so called second digital dividend, which assumes use of the band above 700 MHz for mobile services and data transmission. The built-in filter ensures that unwanted signals in the band >700 MHz will not be introduced into the system.

Due to relatively high gain in THE passive mode, the antenna is suitable for use in SMATV systems and at longer distances from the transmitter. It will prove useful as an element in MATV (DVB-T2) and SMATV (multiswitch) systems.

The packaging dimensions of the Y3 PASSIVE COMBO antenna are: 56 x 24 x 11.5 cm. This is one of the more compact packages among this type of antenna on the market. This seemingly insignificant fact should please every installer who finds it cumbersome to transport large antennas in larger quantities or with other installation accessories.
