Microlab DN-x1FN series of Tappers unevenly split high power RF signals in fixed ratios from 100:1 to 2:1 with minimal reflections or loss. The Tappers cover VHF, UHF, TETRA, and 700 – 900 MHz Public Safety bands. The innovative asymmetric design ensures an excellent input VSWR and coupling flatness across the specified bands.
The lightweight design allows easy attachment to a wall using the supplied bracket. Designed with only a few solder joints and an air dielectric, loss is minimized and reliability enhanced. See DN-x4 series for similar Tappers with broader bandwidth and multiple connector options.
