Welcome to one of the premium manufacturers of FM and TV transmitters-ALLINK. Since starting the design and manufacture of FM broadcast transmitters and television transmitters in 1993, ALLINK has now become one of the top 10 manufacturers and solution providers of transmitters in the domestic market. Be it the FM broadcast transmitter or the television transmitter or even the digital TV transmitter - we manufacture them all. For the last 20 years, we have come up with many innovative FM & TV transmitter equipment.
In addition to the manufacture and service of our primary line of equipment: The broadcasting, analog and digital TV transmitters, we also provide other products and services. Some of our other common products and services are: Digital TV SFN scheme optimization design, new generation Common frequency broadcasting, antenna and feeder system design and installation, UHF RFID reader, UHF RFID module, monitor system and UPS system, CMMB and tags.
Since R & D has been our foundation for the last 20 years, we have become a reliable name in the domestic market for producing innovative equipment in the FM and TV equipment industry. We are proud to be the first digital TV transmitter companies in China to clear the ISO 9001 certification. We are also proud to be associated with an engineering team who has more than 10 years of experience in the TV and FM transmitter industry. We also pride ourselves in being the first company to receive the permit licenses of: The National Industrial products and the State Administration of Radio Film and Television. In fact our reliable and stable range of products and services has helped us win the State Administration of Radio Film and Television bid for 3 successive years: 2011, 2012 and 2013.
