My power lines don't bother me and I don't bother them. Damn battery chargers and the washing machine are another story.


Are you talking typical residential power lines or something bigger? Too many variables and not enough info.


Surrounding objects can cause swr fluctuations but most of the time they shouldn't. When I first started trying to run power in a mobile the swr would change when someone pulled up next to me at a traffic light. Long story short I had a poorly installed antenna.
