Product Catalog

Dear valued customer,

founded 1947 in Munich by Artur Schomandl, our company has a long history and a well reputation for its product range of signal generators based on high stability decade oscillators. Between 1983 and 2013 we were part of the Kathrein Group and extended our portfolio with test receivers, power meters and test sets for professional mobile radio.

Independent since 2013, we have acquired Kathrein’s professional antenna portfolio for frequency ranges between 27 and 174 MHz in 2015. Since then we are the new home of a legendary product range of antennas for professional mobile radio applications. Together with our existing products for antenna testing and our filters and couplers for PMR applications, we are offering a competitive portfolio for nearly every demand.

Schomandl is designing and manufacturing all products in Germany and distributing it under its own brand name.

We are now owned and controlled by engineers and managers with decades of experience in professional mobile radio business, especially in public safety, transport & logistics, maritime radio as well as in industrial & utilities applications. On the following pages, we want to provide you a comprehensive overview of our products. If you need more information or are missing any content, please do not hesitate to contact us at [email protected]

Yours sincerely,

Tapper

• Ruggedized design for use in antenna systems

• 10 dB decoupling over a wide range

• Simple mounting with attached tools

Radio

System

A Tapper is an unidirectional coupler over a broad bandwidth. It works independently of the signal flow with none directional functionality.

The SCHOMANDL Tapper has a frequency range from 150MHz to 2700MHz. This includes the

PMR, WIFI and Cellular bands.

The use is mainly for decoupling RF-signals from a main coax cable installation which is used in

In-House and tunnel radio systems.

The ruggedized design allows an easy installation in nearly all situations either with included mounting plate or mounting bracket.

FIT USB

Through-Line Power Meter for installation tests

Measurement Instruments by SCHNOOR

The new FIT-USB from Schomandl has a large and easy-to-read monochrome graphic display with 240x128 pixel and a touch function.

The new design and compact housing is ideal for a handheld device.

Forward and reverse power (in average or burst mode) or VSWR, by automatic identification­of­CW,­GSM,­TETRA­and­DMR­can­be­ measured simultaneously.

The DC voltmeter with numerical and bargraph display is already built in. So there is no need for an extra instrument

to locate further malfunctions in car installation kits for mobile phones and in the vehicle´s electrical System.

The handheld FIT-Viewer provides easy data exchange and firmware update via USB-Flash

Drive. It is possible to communicate with the

RF-Head via USB from a PC or Notebook – without the handheld FITViewer as well.

The FIT-Viewer is battery operated with long operation and a short charging time and designed to supply the RF-Head, too.

has 3 alarm functions and two alarm levels.

All functions are controlled by pressing the SELECT pushbutton. When SELECT is pushed there is audio and visual feedback.

Changing of alarm level

SI 1000+

can be set to two alarm levels. The lower level is named PUBLIC and is automatically chosen when

SI 1000+

is taken into service.

To change alarm level press and hold down the SE-

LECT pushbutton for more than 5 seconds, where after the response will be 10 long or 10 short beeps.

The chosen level is indicated by a lit bar, when no electromagnetic fields are present.

Measurement Instruments by SCHNOOR

Selecting of alarm function

By pushing the SELECT button, 3 different alarm functions can be chosen:

Normal (one beep)

In this position the

SI 1000+

will give both audible and visual warning, when the chosen alarm limit is exceeded.

Timer (two beeps)

SI 1000+

will only give visual warning, when the chosen alarm limit is exceeded.

After approximately 5 minutes and return to normal position.

SI 1000+

Is it dangerous?

High frequency radiation is known from microwave ovens. The Power and the Time determines how quick and how hot the material gets.

Likewise will other types of electromagnetic radiation influence material near by. This again is a question of power and time when ever it is a health hazard.

WHO has given health hazard limits, these limits are accepted i most parts of the world as standards. The limits are divided into two levels, one for PUBLIC and one for persons trained to work in high frequency radiation areas called OCCUPA-

SIONAL/PROFESSIONAL.

SI 1000+

is used to detect if you are in a high frequency radiation field that could be a health hazard.

SI 1000+

can not give an exact value of the radiation strength or determine how long time you can stay in the radiation field.

When

SI 1000+

gives alarm there is a health risk.

If it is a place of work you should contact the

Security Officer. If you have to work nearby antenna installations e. g. on top of buildings or at antenna towers you should contact the operator.
