Ideal both for point-to-point andmulti-hop connections, these links offer characteristics of very highquality and reliability combined with ease of installation and use "inthe field", thanks, amongst other things, to the new rapid mechanicalassembly systems. All the products, in any frequency range, areequipped with double conversion technology and with synthesizedoscillators which enable 20 pretuned channels to be changed from the RFhead.

On the internal console, a multifunction display allows visualizationof the operating parameters of the unit,
and an LCD monitor on the receiver enables the visual signal receivedto be monitored.

The capacity of the link is 1 video + 4 audio analogue or digitalchannels.

The external mechanical support unit is designed to house two receivingand/or transmitting units which therefore allow the followingconfigurations: RX + RX, TX + TX, TX + RX. This makes it possibleeither to double the capacity of the link itself or to producebi-directional connections.

On the external RF unit, whether receiving or transmitting, are presentthe sealed piezoelectric pushbuttons for channel changing and twohigh-efficiency displays showing the channel and operating frequencyand the output power level or RF input level, so as to facilitate thetracking operations of the system.
The equipment also includes a connector for the coaxial cable linkingthe console to the external unit and an IF monitoring connector.
