DIPOL SMART CITY DVB-T2 DVB-T2 antenna
Packaging
DIPOL SMART HORIZON A2230 is a directional TV antenna designed to receive digital terrestrial television DVB-T2 in UHF band. The antenna is made of aluminum, steel structural elements are galvanized, so they have increased resistance to weather conditions. Black ABS plastic elements ensure stability and aesthetics. Reinforced bar of the antenna guarantees high mechanical resistance (to wind, birds).
The main bar of the antenna is divided into two parts, which makes it possible to shorten it in selected installation scenarios, e.g. when the signal level in the reception area is good, and the antenna is installed on a balcony or in a window. The CITY antenna in the compact version is one of the most compact directional antennas on the market offering good reception performance.
Key features:
  • Designed to receive DVB-T2 terrestrial TV signals in the UHF band,
  • Channels 21-48 (470-694 MHz),
  • Passive or active operating modes,
  • Directional pattern,
  • 2 mounting versions: "full" and "compact",
  • Made of aluminum and ABS,
  • Reinforced main bar,
  • Sealed box with an F-type connector,
  • Tool-free assembly in 3 minutes,
  • Built-in LTE 700 filter.
Installation of the antenna is easy fast and no tools are required. Video installation instructions are available here.
The antenna is equipped with a sealed box with F type connector. The box contains an antenna amplifier with a bypass that allows the antenna to work in two modes:
  • passive – default operating mode. The maximum gain of the antenna is then 10 dBi ("full").
  • active – activated with 12 VDC power supply required (not included). This allows to boost the signal by approx. 20 dB.
DIPOL SMART CITY antenna is extremely versatile due to its well-thought-out design. The installer or user has a total of four antenna operation combinations available: full-passive, full-active, compact-passive, compact-active. The most suitable one can be selected depending on the signal level at the reception site.
The chart shows the antenna gain vs. frequency. Black (letter "P") indicates passive gain of the antenna, while orange ("A"), the active gain. The installer of DIPOL SMART antennas does not have to worry about testing different versions of the antennas by replacing the combiner with the amplifier, or vice versa. During installation and signal measurements, it is enough to turn on 12 V meter in order to verify signal parameters in both antenna modes and choose the most suitable one. For continuous operation in active mode, use the 12 VDC 100 mA power supply
.







Compact dimensions in addition to greater mounting possibilities, ensure no problems in long-term operation (greater resistance to wind, etc.). Compact packaging makes the SMART series antennas easy to transport.
RECEPTION PERFORMANCE PROVEN IN FIELD TESTS

DIPOL SMART CITY antenna has been subjected to many field tests (10 to 100 km from a 100 kW transmitter) before it was put on the market. The tests included measurements in locations with different density of buildings, as well as comparative tests with other DVB-T2 antennas available on the market. Without any major problems, it was possible to receive DVB-T signals at a distance of 50 km from the transmitter (100 kW, low UHF band, terrain profile without any obstacles along the route), with signal strength in passive mode of the antenna averaging 57 dBμV for 3 channels, and the MER value averaging 33 dB. These values should be considered sufficient for building both, individual and SMATV systems.



FAST INSTALLATION WITHOUT TOOLS
It takes less than 3 minutes to install the antenna and no tools are required. Thoughtful design makes it easy to install. The antenna reflector 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.

HIGH QUALITY MATERIALS
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^o^^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.

RECEIVING EVEN 40 KM FROM THE TRANSMITTER
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.
2 OPERATING MODES: PASSIVE AND ACTIVE
The antenna's bypass allows it to operate in two modes: passive and active. This makes the antenna universal, and the installer does not have to test different configurations by inserting and removing the antenna amplifier into/out of the antenna box. To switch to the active mode just connect the 12 VDC 100 mA power adapter with a separator at the TV set. In the passive mode, antenna works without additional power supply.

Built-in LTE filter 700
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.

2 "FULL" & "COMPACT MOUNTING VERSIONS"
The main bar of the antenna is divided into two parts, which makes it possible to shorten it in selected installation scenarios, e.g. when the signal level in the reception area is good, and the antenna is installed on a balcony or in a window. The CITY antenna in the compact version is one of the most compact directional antennas on the market offering good reception performance.

COMPACT PACKAGING
===Dimensions of the DIPOL SMART HORIZON antenna packaging: 58 x 22 x 8 cm. It is one of the most compact packaging among this type of antennas on the market. This seemingly less significant fact should please every installer who finds it difficult to transport large antennas in large numbers or with other installation accessories.
