The high-frequency antenna feeder surge protection device is suitable for the lightning and surge protection of feeder lines and radio-frequency lines,such as GSM mobile base station,PHS base station,satellite receiver and the interphone base station.It also has very low output residual voltage and it can effectively protect receiving equipment,which has high-efficient protection function against lightning high voltage pulse inducted from antenna line. The Standing wave ratio is 1.15, the insertion loss is less than 0.2dB, and the applicable frequencies are 0-400M, 0-900M, 0-1800M, 0-2000M.

Put an arrester in series at the leading end of the line interface of the protected equipment.”OUT” is equipment end and “IN” is incoming line end.Connect the arrester ground terminal and lightning protection ground lead well (suggested earth resistance≤4Ω)
