Electrical safety standards The manufacturers of electronic tools must be taken into account with a several standard for electronic safety and protect the health of the humans and animals. potentially hazardous electromagnetic radiation at microwave frequencies. Few standard were introduced for the harmful impact from high frequency, CB-02 Radio Equipment Radiated Power Generated from Dammam Radio Stations,"1998 Electrical safety standards Electrical safety is a system of organizational measures and technical means to prevent harmful and dangerous effects on workers from electric current, electric arc, electromagnetic field and static electricity. The electrical safety develops with the technical progress. In 1989 OSHA promulgated a much-needed
Electrical length for whip antennas on portable devices such as walkie-talkies to allow antennas much shorter than the standard quarter-wavelength to be used. The most widely used example is the rubber ducky antenna. The electrical lengthening reduces the bandwidth of the antenna if other phase control measures are not undertaken. An electrically extended aerial is less efficient than the equivalent, full-length antenna. There are two possibilities for the realisation of the electric lengthening. Often both measures are combined. The coils switched in series must sometimes be placed in the middle of the aerial construction. The cabin installed at a height of 150-metres
