ETEILY features N-Male and N-Male Lightning Arrestor Adapter with a rubber O-ring seal for mounting through an enclosure wall or the arrester can be used inline. This protector will pass DC, so it is suitable for applications where DC is carried through the coax cable, such as remote amplifiers and LNAs. Both connector ports are equally protected - it can be installed in either orientation. A ground lug on the housing provides superior grounding.

Arresters should be installed as close a possible to the equipment to be protected, often at the point where the coax cable enters the building. They can also be installed near the antenna for additional protection.
