Digital Antenna's innovative DA-2330 2-way amplified satellite radio splitter connects two receivers to one antenna -- perfect for listening to music and monitoring the weather or listening to different music in multiple staterooms. The first and only satellite radio splitter, it simplifies installation while improving performance of XM and Sirius satellite radio systems. The splitter's 10dB gain compensates for cable loss, allowing longer cable runs while maintaining clear signals. Power is supplied from any of the radios connected to the splitter's output via Digital Antenna's auto power detection circuitry.Manufactured for harsh marine environments, the DA-2330 features a durable black powder-coated finish and high quality gold plated mini-UHF female connectors. A double mini-UHF male adapter is also included for easy connection to Digital Antenna's 233-XM-50 Satellite Radio Antenna.
