HTDV Antennae Issues

[jeromebernardjames]

Have the MOHU antennae. Reception is generally great but the received signals change from day to day and within the day.
- The antenna has USB cable which fits into an adapter for power... the ground plug surfaces have been cleaned to include the ground counterpart in the wall outlet yet with some channels touching the coax cable eliminates interference. This suggests that grounding is problematic.

- Also, there a power cable for another appliance that runs parallel to the antennae cable... Is there much of an electrical field that might interfere with reception? if so, looking for an inexpensive material to eliminate reception problems. Guidance sought.

You don't want a power cable running in parallel to the antenna cable. It would create a field. Separate them if only to see if the problem goes away.
If you can't leave them apart then you could try wrapping aluminum foil around the antenna lead and grounding that.
