Made specifically for E&M applications.

To protect an E&M port properly, the audio lines should be protected at a different clamp voltage than the E and M leads. The REM-Surge pictured below, is specifically made to protect E&M ports. It features precise control of transients & high surge current capacity. Completely modular for fast, easy installation. Expandable protection for one to an unlimited number of ports.

Surge suppression is an important consideration when installing a router at a radio site. Antenna structures attract lightning. Good radio system design includes proper grounding, lightning protection and surge suppression at all possible points of entry. 

Protect your router's E&M ports from damaging transients.
