TECHNICAL CHARACTERISTICS TECHNICAL CHARACTERISTICS

• 1 Video and up to 4 Audio. The MLP Series microwave links are designed to carry 1 video and up to 4 highquality 15 kHz analog audio programs. • RF converters. The RF up-converters (HMT/P) and down-converters (HMR/P) are fitted into outdoor waterproof boxes suitable to be fixed to a tripod head. • Control units to RF units cable interconnection. The outdoor RF units are connected with the indoor IF • Easy IF repeater assembly. A non-demodulated IF repeater assembly is obtained using a receiving downchannel: the IF channel selective filters in the IF repeater unit allow to clean the received spectrum from any interference for a good repeater working also in congestioned RF spectrum conditions. • Synthesized RF channels. Easy and fast RF frequency channel setting using a 125 KHz step digital low• Data channel. High capacity data channel is available using the baseband in/out facility or a dedicated data
