Bolton Technical 6 dB Coupler, 698-2700 MHz, Low-PIM, N-Female

The Bolton Technical 6 dB Low-PIM coupler (also known as a tap) is an extremely low loss, high quality coupler designed for multiple indoor antenna runs.

PIM stands for Passive Intermodulation and is measured in dBs (decibels). PIM is defined as the unwanted signal or signals generated by the non-linear mixing of 2 or more frequencies. High PIM means poor cellular reception and limited bandwidth to the end user, which in turn means lost customers to the carrier. Low PIM means strong signals with more bandwidth for more users - in other words, better signal and lower loss across your coupler, providing increased performance.

A 6 dB coupler is best used for dropping antennas as it has a low amount of loss at the point of connection but higher loss at the passthrough.

This allows two indoor antennas to be used with a single amplifier, with the ability to focus more signal to a specific area. They allow for longer cable runs down hallways and across rooms. A 6 dB coupler is ideal for dropping antennas as it has the lowest possible loss at the point of connection.
