Installations with Unstable Power Inputs

There are cases where the device has to be wired to the same power

source as other equipment. In such cases if equipment such as motors

that are connected in the circuit draw a large amount of current during

operation, the transient voltage drop could potentially cause the AWK to

become unstable. Installing a DC/DC power isolator in between the two

equipment is recommended to isolate the transient effect and to ensure a

stable power input for the AWK.

Installations with Cable Extended Antennas for Outdoor

Applications

If the antenna or the AWK device is installed outdoors or in an open-air

setting, proper lightning protection is required to prevent direct lightning

strikes on the AWK device. In order to prevent coupling currents from

nearby lightning strikes, a lightning arrester should be installed as part of

your antenna system. Ground the device, antenna, as well as the arrester

properly to provide maximum outdoor protection for the device.
