Top Signal TS421061 6 dBm Coupler with 1.5 dB Passthru and N-Female Connectors (50 Ohm) diagram How the Top Signal TS421061 coupler works (click to enlarge)

Couplers (or taps) and splitters both divide the signal from a single coax cable into two or more runs. Splitters divide the signal equally, while couplers send a smaller amount of signal to an antenna, and a greater amount further down the line to another antenna, a splitter, or more couplers.

Couplers are typically used in commercial signal booster installations, where the amplifier provides sufficient signal strength to handle the loss involved in tapping a cable. Couplers may also be used in some consumer and residential applications; please contact us to find out if a coupler will work with your specific setup.
