Description
The surge protector is a lightning arrestor of coaxial construction. This device designed to absorb the surge of lightning strikes on an antenna at the top of a building and ground it,thus providing full lightning protection for transceivers,receivers,etc.
Features
- 1. Designed with a stress on high safety,this device has a built-in gas-charging surge arrestor element which discharges and ground the surge at the moment the surge voltage exceeds a specified level.
- 2. This device makes the actions of surge discharge discharge and restoration as repeatedly as necessary.No replacement is practically needed.
- 3. Should the surge arrestor element be damaged,it can easily be replaced with a new element.
- 4. The coaxial costruction of this device assures excellent high frequency characteristics,wide bandwidth,and low loss and VSWR.

Operation
Under-the-eaves application
1. When using the lightning surge protector under the eaves,connect it with an antenna cable.For connection,mount a plug(male) connector on both ends of the antenna cable.
2. Clinch or solder a copper wire,2.5 to 3.2mm diameters, and connect top ens of the wire to lightning escape ground buried deep in the soil ground. It is recommended to connect the lightning surge protector and the ground as short as possible.
3. Be sure to ground lightning protector firmly by taking the following Precautions into account. It is recommended to refer to a book on grounding or consult with a speacialist in the field.
u Use isolated independent groud. Do not share the ground with power line safety ground which is used to avoid electrocution.
u Make ground resistance as small as possible.
u Make ground plate area wide as possible to allow the plate to contact with earth soil as wide area as possible by burring wide copper plate.
u Isolate the ground as far away as possible with other grounding.
4. Since the lightning surge protector are not waterproof locate them on the place where is not expose to direct rain fall or if they may exposed to water, tape them firmly with water resistant adhesive tape.
Caution
1. TO inspect or replace the surge arrestor ,turn an luminum knob with a hand, slant the device and take it out . When tightening the knob, use a fingertip rather than a tool.
2. When using a tall antenna tower,ground the base of the tower with a thick wire(e.g.,a copper wire,over 30 mm2 or an aluminum wire, over 50mm2 ,in cross section).mount a coaxial lightning arrestor beneaththe antenna ,and ground the arrestor through the tower .In this case ,apply an adhesive tape to the arrestor for weatherability.
3. Though the lightning surge protector are very effective to protect from surge voltage caused by thunder lightning, they can not prevent high voltage and current caused by lighting stroke. To prevent thunder stroke, install thunder conductor with thick cable described above and connect them to ground ords.
