    25 kHz frequency grid enables to use only hybrid transmitter combiners. It`s sometimes essential to use power amplifiers, when the number of channels is 4 or greater. In this case transmitter combiner should be meant for greater power input. Here ferrite 300-watt isolators can be implemented. High wattless power coaxial air capacitor usage makes isolator tuning easier and lowers its loss to minimum.
    300-watt isolators are mainly adopted for constructing antenna section of powerful paging transmitters, in order to lower intermodulation interference and protect power amplifier from failure in antenna system. Replaceable ballast load enables to use IF-1(2)V(A,U)-300 for transmitter combiners manufacture, as well as standalone device.
