Instruction Manual
To use the unit properly, read the instructions thoroughly before
installing the unit. Keep the instructions at hand to refer to it if
necessary.
Caution
1. To avoid shock, do not touch the unit and a coaxial cable being
connected to the unit after the thunder lightening starts.
2. To avoid damaging radio equipment from thunder lightening,
disconnect a coaxial cable from the equipment and keep it
away as possible from your reach, preferably outside, if the
equipment is switched off for a long time.
3. To install the unit, be sure to provide stable foot step to
avoid falling down or slipping off from a ladder,
4. To avoid injuring other people, do not drop the unit, parts,
or tools.
5. To avoid falling,slipping,or injuring,do not install or inspect the
unit under bad weather condition.
6. To avoid causing fire,shock,or injuring,do not connect ground
the unit to a gas pipe or water pipe.
Note
1. Do not share the ground line with other utility ground lines such
as power line. It is recommended to separate the unit's ground
line from ones in other systems to avoid malfunctioning the unit.
2. Though the unit is designed to work well to protect radio
equipment from high surge voltage caused by the static
electrocutions or thunder lightening, it cannot protect the
equipment from high current and voltage caused by a thunder
strike itself. To protect the equipment from the strike, install
proper thunder conductor separately.
Features
1.To achieve maximum safety, the unit employs builtin pressured
gas tube surge arrester element to discharge and ground the
surge current when it exceeds predetermined discharge voltage.

2.The unit starts discharging at predetermined voltage and stops
discharging repeatedly as necessary. It is practically no need to
replace the unit. And, if the unit is broken by chance, it is easily
accessible to replace the unit without calling a service.
3.Coaxial structure of the unit allows the unit to have good RF
performance, broad bandwidth, Iow insertion loss, and low
VSWR.
Installation
1.It is recommended to install the unit at the place where has easy
access to the grounding point such as the place where a coaxial
cable is fed into the building.(Fig 1)
2.Crimp or solder a copper wire, with 2.5 to 3.2mm diameter, to a
grounding lug and connect the other end to buried earth ground.
It is recommended to make the grounding line as short as possible.
☆To make good surge grounding
take the following precautions in mind and refer to those books
specialized in grounding, or consult with specialist.
-Make grounding resistance as low as possible.
-To make ground contact are as large as possible,
use electrode such as copper plate as large as possible.
-When the antenna is installed on a tower high above the ground,
ground the base section of the tower with thick wire (more than
30mm copper wire or more than 50mm cross sectional area
aluminum wire). Then install the unit at right below the antenna
and connect the unit's earth section to the tower to use the tower
as effective grounding line.
