The Delta Meccanica 20071 Double Cavity FM Filter with 7/16DIN on both input and output (EIA 7/8 optional) is used for transmitters of up to 1200 watts to prevent the products of intermodulation caused by multiple FM transmitters that are used in the same location or in close proximity to one another.
Preventing intermodulation can be achieved by placing a cavity filter on the output of each transmitter. A double cavity is suitable for a maximum frequency separation of 2 MHz; otherwise, a triple cavity filter is required. Adjust the filter according to the output capacity of the transmitter or power amplifier.
