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

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.

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.

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'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.

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.

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.
