When calculating dB loss you may enter 0.5 dB as the loss from this lighting arrestor.

ALFA ALR6 is an N-male to N-female lightning protector for outdoor antennas. It has a frequency range from 0 to 6 GHz, meaning it can protect any type of outdoor antenna in this range, including 915 MHz, 2.4 GHz and 5 GHz Wi-Fi antennas, and many cellular antennas as well. This does include a gas tube, but does not include a grounding rod.  

Why get a lightning protector? If you have an outdoor antenna, and lightning strikes it, the resulting surge could be harmful to any equipment you have attached to the antenna via cable, such as Wi-Fi receivers or wireless routers/access points. Boaters and RVers are especially vulnerable to lightning strikes with tall outdoor antennas. This lightning protector goes in between the antenna cable and the antenna (outdoors) and should not be used indoors between the receiver and cable.
