The JN1105A is a mobile communication countermeasures system designed to locate and jam enemy tactical radio communication signals. The system was developed by 36 Institute (now Jiangnan Electronic & Communications Research Institute, JECOR) of Jiangxing, Zhejiang Province in 1982. The JN1105A took part in the 1980s China-Vietnam border conflict and played important roles in the electronic warfare to suppress Vietnamese Army command & control and communications networks.
The system can cover the communication frequencies of HF (1.6~30MHz), VHF (30~100MHz), and UHF (100~500MHz). The whole system is carried on a vehicle, but can also be dissembled and carried by several soldiers on specially-designed racks to reach remote areas in mountain and highland.
