COMPANY PROFILE Founded in Milan in 1935, UNAOHM is one of the oldest manufacturers of measuring electronic equipments all over Europe. It was born thanks to two young engineers, Mr Enzo Pontremoli and Mr Giovanni Bozzi. In the early 60 s the trademark is registered. In 1956 UNAOHM begins manufacturing an instrument dedicated to installers of TV-reception systems, that is the field strength meter, immediately becoming the main player of this sector. All efforts of the R&D division are put into the Field Strength Meter. At present a complete range of equipments is offered, including handhelds and professional meters to thoroughly analyze all TV signals, both digital and analogue; some models can also measure signals of fiber-optic distribution. Business The company s activities concern several fields of electronics and telecommunication and are divided as follows: Field Strength Meters and Lab Equipments division Inside this division we carry out research, development and design of field strength meters and accessory equipment (noise generators, reflectometer bridges, etc.) for installation of reception systems (terrestrial, satellite and cable TV signals). Radio System division It carries out the production, installation and maintenance activity of professional radio links designed to work in hostile environments, such as oil-extraction platforms. Equipments for Photovoltaic Installations division This division has been dealing with the design of equipments for photovoltaic plants for a few years. These instruments enable to test and certify according to the European regulations. Services The company offers several services for pre-sale and after-sale technical support to help choose and use the instrument. Moreover, we monthly arrange updating courses about new technologies for TV broadcasting, their measure features and techniques for reception and installation.

The noise generator NG 600 is an external module used for many applications as settings the filters, settings the cable, calculus of the distance of fault on the cable. The NG 600 is light, cheaper and easy to use. It has an internal battery with running time of 7 hours. It is suitable with every field strength meters and with UNAOHM instruments has special function as CLC function. CLC function: calculus of the distance of fault on the cable
The Frequency Converter FCV300 EVO is an external module that combined with a field strength meter, displays frequencies between 2000 MHz and 3000 MHz. The main measurable signals are Bluetooth, Wi-Fi, MMDS and others signals in this frequency band. The displays of converted carrier will be into IF SAT band ie in the range of frequencies between 1000 MHz and 2000 MHz. If the field strength meter has the Max Hold function, you can see the random signals (not continuously present), otherwise they are impossible to measure for their inconstancy. The size is small and weight is very low, the power supply is between 13 and 18 volts, it is applied directly to the RF output connector of the field strength meter.

TRAINING COURSES FOR INSTALLERS UNAOHM continues with the tradition of free training for installers at its headquarters in Peschiera Borromeo. The duration of the course is one day, from 9:30 to 16:00 according to the requests of the participants. The dates for 2018 are as follows: JANUARY 25 FEBRUARY 22 MARCH 22 APRIL 19 MAY 17 JUNE 28 JULY 12 SEPTEMBER 27 OCTOBER 25 NOVEMBER 22 DECEMBER 13 Course topics: The UNAOHM training course analyze the technical characteristics of a TV system, of television signals, and of the equipment information. The measurements and information provided by the instrumentation are described for evaluate if the system works properly, revealing any defect and indicating concrete procedures for solving them. The course provides a theoretical part and a practical part to learn how deal with problems in a concrete way. A lot of time is for the requests and arguments put forward by the participants. At the end of the course a certificate of participation is issued.
