As the NTS-antenna is a roof mounted device to ensure clear view of the sky. Therefore, it is likely to be exposed to lightning strikes. The lighting protection NTS-protect is set of 1 -3 surge arrester(s) mounted to protect and to isolate your NTS server from antenna upon bad weather conditions. The NTS-protect has been designed so to be in compliance with regulation No.75 Journal of Laws, June 15, 2002, items 180, 183, providing that wiring systems should secure against switching overvoltage and lightning surge, and that voltage limiters shall apply thereto.
There are 3 configurations:
1) NTS-protect-1 (std) – the single arrester
2) NTS-protect-2 (mid) – the double arresters
3) NTS-protect-3 (max) – the triple arresters
