Introduction

Congratulations on purchasing the Samson DA40 Antenna Distribution system. The DA40 allows
up to four UHF wireless receivers to share the same pair of antennas. The wide band system can
work with wireless systems from 470 MHz to 1 GHz. With four DC power output jacks, the DA40
facilitates more compact setups by reducing the number of cables and antennas needed. The 6dB
of RF gain makes up for any insertion loss. For permanent installations or transporting in a mo­bile rack, the DA40 can be mounted into a single rack space using the included rackmount kit.

In these pages, you’ll find a detailed description of the features of the DA40 Antenna Distribution
System, as well as step-by-step instructions for its setup and use. If your Antenna Distribution
System was purchased in the United States, you’ll also find a registration card enclosed—don’t
