FM Dummy Loads

Dummy loads are used to facilitate the off-air full power testing of an FM transmitter in the event that the main transmitter or auxiliary transmitter fails and needs to be taken off the air for repair, servicing and eventual restoration to on air status. Kintronic Labs offers a line of forced air cooled FM dummy loads having an input impedance of 50 + j0 in the DC-110 MHz band. The Kintronic dummy loads are offered in indoor or outdoor weatherproof designs and are rated for transmitter input powers ranging from 5kw to 75 kw. Each Kintronic dummy load can handle Peak Envelope Power (PEP) of up to twice the average power rating. However, higher peak powers, including pulse applications, require special consideration involving peak voltage and current, and peak energy levels.
