Antenna AT2S

The AT2S-type antenna has been designed to meet extreme technical and environmental requirements introduced by the rail rolling stock industry. It is a unique device developed by Radionika, offering reliable GSM-R/GSM digital radio signal reception & transmission with a high-quality GPS receiver provided.

The electrical and mechanical structure ensures that operation parameters are optimal and the device ready for use alongside radio communication equipment used in locomotives and trains, i.e. GSM-R radio terminals, GSP receivers,  GSM terminals, etc. 
The mechanical assembly of the antenna provides high resistance to harsh environmental conditions present on railway tracks, especially to extreme temperatures, heavy rains and mechanical impacts.
