New Triax GHV 940 distribution amplifier
- Triax GHV 940-series is a low noise coaxial house distribution amplifier, for use
in medium to large CATV distribution networks in multi-dwelling houses, (NE4).
The GHV 940-series distribution amplifier has a modular
design with return path all-on-board for easy setting and
installation, yet is also fully configurable using plug-in
modules. Rotary switches and jumpers provide for
readable, easy and reproducible setting of attenuation
and equalization, maintaining a non-breakable signal path
down- and upstream to avoid down-time.
• Optimised 1 GHz technology
• Up to 40 dB downstream amplification/high output level
• Adjustable attenuation and equalization settings
in 1dB steps using rotary switches and jumpers.
• All-on-board return path technology, all features
available without module.
• Upstream 22/32 dB amplification/High output level
• On-board return path and diplexer can be replaced
by a plug-in module in case of damage caused by
a surge or lightning.
• Adjustable attenuation and equalization settings
in 1dB steps using rotary switches and jumpers.
• Switchable VHF band I (RC=OFF) or
5-65 MHz return path (RC=ON)
• Selectable return path: On/Off, Active/Passive.
• Other return path and diplexer specifications
available by mounting a plug-in module.
• Automatic return channel activation (ARA). Switchable
return channel blocker for noise suppression.
• All connectors are F-connector female, individually mounted.
• - 20dB input and output test connectors
• Extensive ESD- and surge-protection
• Unit is mains fed via an EU-type power plug.
• Low power consumption
