The voltage should be between 12VDC and 21VDC.

Coaxial cable to the TV set connects to the TO TV port on the power inserter.Coaxial cable from the preamplifier connects to the TO AMP port on the power inserter.Connect the coaxial cable going into the house to the OUTPUT/POWER port on the preamplifier.Antenna output goes to the INPUT port on the preamplifier.Verify all connections are correct and tight.Troubleshooting steps for individual items are listed below. If it is, you have identified the equipment that is causing the problem. When the channels are lost, remove the last piece of equipment that was installed and make sure everything is still working.
The quickest way to determine which piece of equipment is causing the issue is to reinstall the equipment one piece at a time that was removed in step #6 above, and checking for channels on the TV set after each piece of equipment is reinstalled. If you do have TV channels after step #6 above, the troubleshooting steps to take next will depend on what other equipment is included in your installation. Your antennas performance can become degraded over time if elements, or the interconnections between the elements become damaged, but total failure is not common. This however is not common for an antenna to fail completely. If this doesn’t resolve the issue then it may be necessary to replace the antenna. If there still are no picture, try replacing the balun/matching transformer. If you still don't have any pictures on any channels after step #6 above, try a different coaxial cable between the antenna and the TV. If you are able to receive even one channel without the preamplifier, don’t include the preamplifier for this test since it is designed to eliminate as many possible failure points as possible.
If you live in an area where a preamplifier is required to receive any channels, then leave it in place for this initial test. If possible connect a cable directly from the antenna to the TV with nothing else in between(including preamplifiers, amplifiers, splitters, DVRs, VCRs, home theater receivers, or any other equipment and do a channel scan on the TV set to see if you are receiving anything).If you have a second TV, try it to make sure the TV is working correctly.You'll also want to check any other equipment that may be in the installation for any damage, and replace any items that are damaged. Visually inspect the antenna, coaxial cable and the balun/matching transformer (the device that connects the antenna to the coaxial cable).
