Antenna Isolator Installation Guide

y

- Use this to install TV in a place where there is a voltage difference between TV Set and GND of
antenna signal.

»If there is a voltage difference between TV Set and GND of antenna signal, the antenna contact

might be heated and excessive heat might cause an accident.

- You can improve the safety when watching TV by efficiently removing power voltage from TV
antenna. It is recommended to mount the isolator to the wall. If it cannot be mounted to the wall,
mount it on the TV. Avoid disconnecting the antenna Isolator after installation.

- Before starting, be sure that the TV antenna is connected.

“Equipment connected to the protective earthing of the building installation through the mains
connection or through other equipment with a connection to protective earthing - and to a cable

distribution system using coaxial cable, may in some circumstances create a re hazard. Connection

to a cable distribution system has therefore to be provided through a device providing electrical
isolation below a certain frequency range (galvanic isolator, see EN 60728-11)”

When applying the RF Isolator, a slight loss of signal sensitivity can occur.
