The STRATA-HS Transmitter delivers high quality video using MPEG Encoding (4:2:0) and COFDM modulation, a field proven technique for uninterrupted in video, even dense urban areas.

The TXU-HS uses a single front panel push button/rotary switch to perform common functions, as well as change settings. An LCD displays operating parameters.

From a PC or laptop, use the STRATA-HS Configurator Software to create, modify, and store configuration "presets" to be recalled using the front panel switch. The TXU-D uses a standard "N" type RF connector providing for cabled or direct mounted antennas. The optional Twist Lock

Adapter mounts over the RF connector to let you easily install or remove a variety of MRC's Parabolic or MegaHorn antennas, eliminating the need for coaxial interconnecting cables.

STRATA Configurator

STRATA Configurator lets you create, modify, and save several system configurations in storable presets prior to taking the system to the field.

This feature is helpful for setting either analog or digital configurations, frequency, channel offset, and modulation schemes. Setting system presets can be a time saver when you need to quickly set up at a remote location, or recall configuration presets at locations you tend to use often.
