RF DA Distribution Amplifier

Designed for field and film use the RF DA is a compact, active distribution amplifier for antenna and DC of UHF wireless. It boasts a bandwidth of 200 MHz (500-700 MHz) with very good RF filtering above 700 MHz and below 500 MHz to reduce the risk of interference from 4G at the higher frequency end. There are two antenna inputs on the top panel. Each antenna input feeds 4 x SMA outputs. Each output has a gain of approx. 2-3 dB. Switchable 8V DC supply for Audio's Masthead Amplifier. Hirose 4-pin DC Input and Hirose 4-pin DC sockets to power receivers and mixers.
