MW-EM-860-R(20) - E(M) series 860MHz LINE DISTRIBUTION
   MW series of 860 MHz Line Distribution are typically deployed in the feeder or tapped portion of the RF network. Configurable as either a single or dual output device, these amplifiers provide a flexible, cost effective product platform, and are readily adaptable towide-ranging design application.
   MW series of 860 MHz Line Distribution are available in multiple fixed gain versions and are ideally suited for new build and rebuild cons truction. They are gain-targeted and specifications-targeted for direct drop-in retrofit in 860 MHz transitional upgrades. All 860MHz active electronics offer improved performance, realiability and accessibility.MW series of 860 MHz Line Distributionhave two separate test ports for forward and return RF signal. The second output port optional
