Leaky Feeder
System
We communicate underground and surface with equipment specially manufactured for these environments
- Avoid noise
- Redundandant
Leaky Feeder units
VHE: Head End
It distributes all the information to spread communications signals on the surface and underground.
VLAD: Amplifier
It keep up signals for clear communications
VBU1: Single Branch
Splits LF cable on two, protecting signals
VBU2: Double branch
Splits LF cable on three, protecting signals
VLT
Line termination
VSA
Antenna Stope
PSU
Power supply with battery backup
LFC: Leaky Feeder Cable
It allows wireless communications where it runs along tunnels
How Works
The system heart is the Head End, it sends voice and data communications to the tunnels using leaky feeder cables, providing for underground and surface wireless communications. To keep communications clear and distinguishable, it is required to include amplifiers every given sections. If extra tunnel needs communications, it is required to branch cables, using Branch units.
