TV-FM SYNTHESIZED MICROWAVE LINKS
Mod.
BICR-AV/7,5
The Link Series
BIC-AV/7,5 operates in the microwave band with FM carrier, rated output
power up to 1W and broadcasting capability of one video signal and up to four sound
signals.
The
BIC
System complies with the CCIR rules, that impose the I.F. of 70 MHz.
The modular design allows great flexibility and easy access for the maintenance, and its
cabinet allows 19"-3U rackmount in small and medium environment.
It can operate with power supply from electric network or external battery.
The 7,5GHz links are also available with aerial heads mounted directly on the parabolic
antenna.
