Antenna AT2S

Multi-band GSP/GSM-R/GSM antenna type AT2S has been designed to meet extreme technical and environmental conditions existing on rail rolling stock industry. It is a unique, developed by Radionika, construction offering reliable digital radio GSM-R/GSM signal receive & transmit with implemented high quality GPS receiver.

Electrical and mechanical construction offers optimal parameters for use together with radio-communication equipment used in locomotives and trains, i.e. GSM-R radio terminals, GSP receivers,  GSM terminals, etc. 

Mechanical construction ensures resistance to harsh environmental conditions existing on rail track, specially high and low temperature, heavy rains and mechanical impacts.
