Product Description

Product Summary
  WF1100E outdoor unidirectional amplifier is mainly used for the transmission of 
CATV television image signal, digital TV signal, telephone voice signals and data 
(or compressed data) signal. Advanced and mature circuits, scientific and 
reasonable process structures and high quality materials, ensure the excellent 
performance. 
 
Performance Characteristics
 1.1003MHz bandwidth design. 
 2. It is more convenient to debug because of the plug-in equalizer, attenuator, output tap and
 the scientific and reasonable on-line detection ports.
 3. The equipment can long time continuous work steadily under outdoor bad 
environmental condition. Because of the aluminum waterproof housing, high reliability 
switching power supply and strict lightning protection system.
