Typical applications:• Satellite operators, VSAT,teleports and broadcasters• High resilience RF
distribution and optimum
satellite signal quality• 850-2450 MHz to cover Kaband and HTS applications

The Dextra splitter range has been designed for high resilience RF distribution, and optimum satellite signal quality.
The splitter benefits from excellent RF performance, compact form factor as well as being a highly resilient solution
minimising the risk of expensive downtime for the satcoms user
