Blister equipment high frequency output high intensity fundamental wave

In addition to outputting high-intensity fundamental waves and harmonics, the high-frequency machine also has high-order harmonics with considerable intensity. Each high-order harmonic of the fundamental wave may interfere with the TV programs of the corresponding channels. Experiments and observations were made on several TV sets adjacent to the machine, which proved that the TV image or sound layer of the corresponding channel was disturbed to different degrees. Through testing and observation, it is believed that the fundamental and harmonic frequencies of the high-frequency machine are lower than 45MHz, which will not interfere with the cable TV outside the cable TV frequency band. It is their higher harmonics that interfere with the cable TV.
