Power injector
Choose a place inside the cabin where to place the
power injector to protect it and taking care with
the cable length, it shouldn’t be excessive from the
antenna to the injector and from the injector to the
TV.
The cable connection with the antenna and the
injector is made through “F” connectors while
the connection to the TV is made through an IEC
connector, which is mounted as indicated in Fig. 5.
Connect the cable from the antenna to the
connector on the injector with DC pass. Connect
the cable to the TV to the connector with the DC
pass blocked.
Make sure that the cable is not wound round too
many times, and that it does not have any kinks.
Operating mode
Powered using a battery or DC source (12...24
V ) using the power injector supplied together
with the antenna, you can activate the
BOSS-tech
system.
If the signal was very high, it is also possible to
use the antenna in passive mode ( BOSS-Tech off),
connecting directly to the TV.
Tune in your TV with the UHF channels received
in the area. Observe the image on the screen
and choose the operating mode for the antenna
depending on its quality.
Troubleshooting
FAILURE CHECK ACTION
- There is neither picture
nor sound.
- Channel not tuned in the TV
set correctly?
- Is the battery connection OK?
- Tune the TV set to the local TV channels.
- Check installation cable and connectors: there might
be a shortcircuit. (Check that there is DC voltage at
the PSU’s antenna connector).
- Check if the red wire is connected to positive and the
black one to negative. If connections are OK, then
check the battery condition.
- The current flow connector is connected to the
antenna and the connector locked to the TV.
- Problems with picture/
sound.
- Obstacles in front of the
antenna?
- Poor signal?
- Remove the obstacles or change the antenna
location.
- If there isn’t obstacle, power the antenna and / or
check that power is supplied.
