WAVENET Mobile radio-link transmitter BS-5000
The Wavenet BS-5000 base transmitter is a long range broadcast quality audio radio link, designed for an easy handling and high reliability.
BS-5000 transmitter has a RF power above 30W with up to 200 selectable working frequencies (174 to 500 MHz- 40MHz window). This device has been made using the highest current manufacturing standards. It has SW controlled protection redundancy developed by Wavenet.
Wavenet BS-5000 also has 5 inputs with switchable micro-line gain selector. This versatility allows you to virtually manage with any situation.
It has a complete backligthed display with navigation keys acting and posing all parameters, alarms and equipment selections.
This system can be easily transported by mean of a handle buit-in in one of its sides.
Accepts 90-250VAC and 9-36VDC powering, allowing its use in any situation.
It may be optionally remotely controlled by Ethernet.
