Troubleshooting

WARNING: Do NOT install couplers, splitters, etc. between the power supply
and the antenna. Installation of any item on the downlead may cause a short in the
system. The downlead supplies +12 VDC to the preamp in the antenna.
What to do when your RV/TV antenna is not working properly:
TO TEST SYSTEM –
Step 1 – Make sure TV set is working properly.
Step 2 – Switch power supply ON and OFF watching for difference in picture quality. If
there is NO difference, use following steps:
CAUTION:
The power supply should be turned OFF when connecting/
disconnecting cables to power supply and antenna, but should be turned ON
when testing for voltage.
Step 3 – Disconnect cable from antenna and check for +12 VDC at Test Point #1. If there
is +12 VDC, the power supply is OK. Replace antenna.
Step 4 – If there is NO +12 VDC at Test Point #1, reconnect cable to antenna. Remove
power supply from wall and visually inspect for burned/broken parts. If there are
ANY broken/burned parts, replace power supply.
Step 5 – Disconnect cable from antenna jack on power supply. Check for +12 VDC at
Test Point #2. If +12 VDC is present, there is a cable problem connecting the power
supply to the antenna. Repair/replace cable.
Step 6 – If +12 VDC is not present at Test Point #2, be sure the green indicator light is
ON. If not, check the polarity of the red/white wires and the +12 VDC source. If there
is still no +12 VDC, replace power supply.
