Directional coupler N jack 20dB 700MHz to 2700MHz (usable from 600MHz) with 200W power handling. Also known as a 20dB RF tap or signal tap, this wideband coupler is designed for distributed antenna systems (DAS), cell phone signal booster installations, and RF power sampling applications. The exceptionally low 0.2dB insertion loss makes it ideal for in-building wireless systems where minimal signal degradation is critical. Covers all 2G, 3G, 4G, and LTE cellular bands including 700MHz, 800MHz, 900MHz, 1800MHz, 2100MHz, and 2600MHz.
