Connecting the Antenna
An outdoor antenna or CATV is recommended for the best reception. The antenna type and its location differ
dependent on local conditions.
It is recommended that a 75Ω coaxial cable be used in order to eliminate possible interference and
noise which may occur due to nearby radio transmissions.
When using a 300Ω twin - lead feeder, connect it to a 300Ω / 75Ω converter and insert the convert-
er into the projection TV’s CABLE IN terminal.
Connect an outdoor antenna referring to the above figure. Set up a lightning arrester and check it
regularly when an outdoor antenna is used.
The antenna cable should not be tied together with other wiring.
The two RF jack allow you to switch signal between Cable and Air input.
